Question

54) A 5.0 L sample of an ideal gas (MW 62.54 g/mol) was collected at 1.3 atm and 25 C. What is the density of the gas? a) not enough information b) 40 g/L c) 47 g/L d) 3.3 g/L e) 188 g/L

Answer 1

To calculate the density of a gas, we need to know its molar mass and volume. In this case, we do not have enough information to calculate the density of the gas.

Step-by-step explanation:

To calculate the density of a gas, we need to know its molar mass and volume. In this case, we have the molar mass of the gas (62.54 g/mol) and the volume (5.0 L). Using the formula density = mass/volume, we can calculate the mass of the gas.

mass = molar mass × moles

moles = PV/RT

Using the ideal gas law, PV = nRT, we can solve for moles. Then, substitute the moles into the mass formula to calculate the mass of the gas. Finally, divide the mass by the volume to get the density.

In this case, we do not have enough information to calculate the density of the gas, so the answer is a) not enough information
