Andre, a physics undergraduate, enters a coffee shop that is holding a contest. Customers who guess the number of coffee beans i

nside of a closed, 16.0 fl oz aluminum commuter mug get a free pastry and an espresso drink. Motivated by the prospect of free food and coffee, Andre puts his finely‑tuned estimation skills to work. Andre assumes that a typical coffee bean is about 1 cm long. Based on that assumption, what should Andre submit as his estimate for the number of coffee beans in the mug?

Answer: 8 coffee beans

Explanation: this calculation can only be achieved if you are good

With your conversation table.

16fl oz is the same as 16 US fluid ounce. The question is to determine how many centimeter can be equall to 16fl oz.

Stage 1:

Convert 16 US fluid to milliliter

1 US fluid = 29.574mililiter.

Therefore (16fl oz × 29.574ml)÷ 1fl oz= 473.184ml

Stage 2:

Convert milliliter to cubic centimeter

1 milliliter = 1 cubic centimeter

Therefore 473.184ml= 473.184cc

Stage 3:

Convert cubic centimeter to centimeter

1 Cubic centimeter is the volume 1 centimeter of a length side occupies

Volume= the length of the three sides of a shape.

Therefore

Volume= lenght^3

Making length the subject of the formula it becomes

Length =Cube root of volume

Length= 3√volume

Therefore

Length = 3√473.184= 7.793cm

Approximately 8cm

This means the mug is 8cm in length

Stage 4:

Since Andre assumption is that coffee Bean is about 1cm and from the calculation the mug is 8cm, which means about eight coffee Beans will fill the flask.

Andre should submit 8 coffee beans

What is the mass of 22.4 L of H2 at STP?
Vanyuwa [196]

A. 1.01 is the right answer

Since

The formula is Pv= nRT

P=1 atm

V= 22.4 L

N= x

r= 0.0821

t = 273 k (bc it’s standard temperature)

So (1)(22.4)=(x)(0.0821)(273)

X= 1.001

How many moles of koh are contained in 750. ml of 5.00 m koh solution?
Marat540 [252]
Molarity is one of  the method of expressing concentration of solution. Mathematically it is expressed as,
 Molarity = \frac{\text{number of moles of solute}}{\text{volume of solution (l)}}

Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l

∴ 5 = \frac{\text{number of moles}}{.750}
∴ number of moles = 3.75

Answer: Number of moles of KOH present in solution is 3.75.

Perform the following calculations and give your answer with the correct number of significant figures:
Arte-miy333 [17]
When multiplying numbers, the term with the least significant digits gives how many significant digits will be in the answer. 2.995 has the least with 4 "sig figs", so the answer will have 4 significant digits as well:

2.995/0.16685 = <span>17.9502547198
</span>                           ↑↑  ↑<span>↑
                        4 sig figs

So the answer is 17.95.</span>

PLS HELP! 50 PTS!
ioda

Answer:

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

Explanation:

<em>The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.</em>

<u>According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.</u>

In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.

Three solutions contain a certain acid. The first contains 10% acid, the second 30%, and the third 50%. A chemist wishes to use
Fittoniya [83]

Answer:

To prepare 50L of 32% solution you need: 11L of 30% solution, 22L of 50% solution and 17L of 10% solution.

Explanation:

A 32% solution of acid means 32L of acid per 100L of solution. As the chemist wants to make a solution using twice as much of the 50% solution as of the 30% solution it is possible to write:

2x*50% + x*30% + y*10% = 50L*32%

<em>130x + 10y = 1600 </em><em>(1)</em>

<em>-Where x are volume of 30% solution, 2x volume of 50% solution and y volume of 10% solution-</em>

Also, it is possible to write a formula using the total volume (50L), thus:

<em>2x + x +y = 50L</em>

<em>3x + y = 50L </em><em>(2)</em>

If you replace (2) in (1):

130x + 10(50-3x) = 1600

100x + 500 = 1600

100x = 1100

<em>x = 11L -Volume of 30% solution-</em>

2x = 22L -Volume of 50% solution-

50L - 22L - 11L = 17 L -Volume of 10% solution-

I hope it helps!
