Volume = Mass / Density

Volume = 540g / 2.70 g/ml

Volume = 200 ml

Answer:

Volume of the cylinder is, V=200\ ml

Explanation:

It is given that,

Mass of the cylinder, m = 540 grams

Density of the cylinder, d=2.7\ g/ml

Let V is the volume of the material. We know that the mass per unit volume of any material is called its density. The mathematical relation is given by :

d=\dfrac{m}{V}

V=\dfrac{m}{d}

V=\dfrac{540\ g}{2.7\ g/ml}

V=200\ ml

So, the volume of the cylinder is 200\ ml. Hence, this is the required solution.

How many moles are equal to 47.2 g of K2O
HACTEHA [7]

Answer: 0.50 mole K2O

Explanation: To convert the mass of K2O to moles we will need to find the molar mass of K2O.

47.2 g K2O x 1 mole K2O / 94 g K2O

= 0.50 mole K2O

Estimate the increase in the molar entropy of O2(g) when the temperature is increased at constant pressure from 298 K to 348 K,
Tamiku [17]

Explanation:

It is known that relation between entropy, heat energy and temperature is as follows.

        dS = \frac{Q}{T}

        \int dS = \int \frac{Q}{T}

Also we know that at constant pressure, Q = \Delta H = C_{p} - dT

     \int_{S_{1}}^{S_{2}} dS = \int_{T_{1}}^{T_{2}} C_{p} \frac{dT}{T}

     \Delta S = C_{p} \int_{T_{1}}^{T_{2}} \frac{dT}{T}

As the given data is as follows.

        T_{1} = 298 K,          T_{2} = 348 K

         C_{p} = 29.355 J/K mol

Now, putting the given values into the above formula as follows.

          \Delta S = C_{p} ln {T_{1}}^{T_{2}} \frac{dT}{T}

                  = 29.355 [ln (348) - ln (298)]

                  = 29.355 [5.85 - 5.69]

                  = 4.48 J/k mol

Thus, we can conclude that the increase in the molar entropy of given oxygen gas is 4.48 J/k mol.

A metallurgist reacts 320.0 grams of 75.0% by mass silver nitrate solution with an excess of copper metal. How many grams of sil
denpristay [2]

Answer:

= 152.40 g

Explanation:

The equation for the reaction is;

Cu(s) + AgNO3 → Ag(s) + Cu(NO3)2

Mass of silver nitrate = 320.0 g × 0.75

                                    =  240.0 g

Molar mass of silver nitrate =  169.87 g/mol

Therefore;

Moles of silver nitrate = 240.0 g/169.87 g/mol

                                    =  1.413 moles

Mole ratio of Silver nitrate to silver metal = 1 : 1

Therefore, moles of silver metal = 1.413 moles

Hence;

Mass of silver metal = 1.413 moles × 107.868 g/mol

                                 <u>= 152.40 g</u>
