1.5 x 10⁶mm³

Explanation:

 Here we are to convert m³ to mm³ or cm³ to see the correct option.

100cm = 1 m

1000mm = 1m

Converting to cm³ from m³;

  0.0015m³ = 1.5 x 10⁻³m³

Now:

    1.5 x 10⁻³  x m x m x m x \frac{100cm}{1m} x  \frac{100cm}{1m} x \frac{100cm}{1m}

    = 1.5 x 10³cm³

Also;

1.5 x 10⁻³  x m x m x m x \frac{1000mm}{1m} x  \frac{1000mm}{1m} x \frac{1000mm}{1m}

  =   1.5 x 10⁶mm³

86.1 g of nitrogen reacts with lithium, how many grams of lithium will react?
Zina [86]

Answer:

128g of Li, will react in this reaction

Explanation:

Before to start working, we need the reaction:

N₂ and Li react, in order to produce Li₃N (lithium nitride)

N₂ + 6Li → 2Li₃N

1 mol of nitrogen reacts with 6 moles of lithium

We convert the mass of N₂ to moles → 86.1 g . 1 mol/ 28g = 3.075 moles

1 mol of N₂ reacts with 6 mol of Li

Therefore, 3.075 moles of N₂ will react with 18.4 moles of Li

We conver the moles to mass → 18.4 mol . 6.94g / 1mol = 128 g

Scientists determine that the wooden beams of a sunken ship have 67 % of the concentration of Carbon-14 that is found in the lea
DerKrebs [107]

Answer:

The age of ship is 1900 years.

Explanation:

The half life period of carbon - 14 is 5730 years

Ship have 67 % of the concentration of Carbon-14

And the ship lost (100- 67 = 33%) 33% of carbon - 14.

Therefore,

The age of ship = lost percentage X half life period of carbon -14

= 33 \times 5730 yrs = 1890.9yrs\equiv 1900\,years

Therefore, The age of ship is 1900 years.

What is the osmotic pressure of a solution prepared from 13.7 g of the electrolyte HCl and enough water to make 0.500 L of solut
kherson [118]

Answer:

P = 17.9618 atm

Explanation:

The osmotic pressure can be calculated and treated as if we are talking about an ideal gas, and it's expression is the same:

pV = nRT

However the difference, is that instead of using moles, it use concentration so:

p = nRT/V ----> but M = n/V so

p = MRT

We have the temperature of 18 °C (K = 18+273.15 = 291.15 K) the value of R = 0.08206 L atm / K mol, so we need to calculate the concentration, and we have the mass of HCl, so we use the molar mass of HCl which is 36.45 g/mol:

n = 13.7/36.45 = 0.3759 moles

M = 0.3759/0.5 = 0.7518 M

Now that we have the concentration, let's solve for the osmotic pressure:

p = 0.7518 * 0.08206 * 291.15

<em><u>p = 17.9618 atm</u></em>

castortr0y [4]
Momentum = Mass x Velocity
80kg Runner: 80 x 2.45 = 196 Kg m/s
65kg Runner: 65 x 3= 195 Kg m/s

The 80kg runner has a greater momentum
