Question

1. a balloon contains 3.7 moles of helium gas. how would you convert this amount to liters of gas? divide 3.7 moles by the molar mass of helium gas. multiply 3.7 moles times the molar mass of helium gas. divide 3.7 moles by the conversion factor of 22.4 liters / mole multiply 3.7 moles times a conversion factor of 22.4 liters / mole

Explanation:

Step1: Recall the molar volume concept

At standard temperature and pressure (STP), the molar volume of any ideal gas is \(22.4\) liters/mole.

Step2: Analyze the conversion formula

To convert moles of a gas to liters, we use the formula \(V = n\times V_m\), where \(n\) is the number of moles and \(V_m\) is the molar volume. Here, \(n = 3.7\) moles and \(V_m=22.4\) liters/mole. So we need to multiply the number of moles by the molar volume (\(22.4\) liters/mole).

Answer:

Multiply 3.7 moles times a conversion factor of 22.4 Liters / mole.
