Mole to Volume Conversions Worksheet
Example #1: Determine the volume, in liters, occupied by 0.030 moles of a gas at STP. (moles to liters)
**STP stands for Standard Temperature and Pressure, Standard temperature is 273 K and Standard pressure is 1
atm.**
0.030 mole (22.4 L) = 0.67 L
**divide first, then multiply
(1 mole)
Example #2: How many moles of argon atoms are present in 11.2 L of argon gas at STP. (liters to moles)
11.2 L (1 mole) = 0.500 moles
(22.4 L)
**divide first, then multiply
1.
A sample of neon has a volume of 75.8 L at STP. How many moles are present? (liters to moles)
2.
What is the mass in grams of a 8.4 mole sample of iron? (mole to grams)
3.
Convert 0.45 g of sodium hydroxide, (NaOH) to moles.
4.
How many moles of potassium nitrate, (KNO3) are present in a sample with a mass of 85.2 g? (grams
to moles)
5.
What is the mass in grams of 0.94 moles of sodium bicarbonate (NaHCO3)? (moles to grams)
6.
Convert 7.8 L of carbon tetrafluoride (CF4) to grams. (Liters to moles, then moles to grams)
7.
What is the volume in liters of 7500 g of helium atoms at STP? (grams to moles, then moles to liters)
8.
One component of smog is nitrogen monoxide (NO). A car produces about 8 g of this gas per day.
What is the volume at STP? (grams to moles, then moles to liters)
(grams to mole)
