Calculate the number of liters in 3.25 g of ammonia

The liters in 3.25 g of ammonia 4.28 L

calculation

Step 1: find moles of ammonia

moles = mass: molar mass

From periodic table the molar mass of ammonia (NH₃) = 14 + (1*3) = 17 g/mol

3.25 g: 17 g/mol = 0.191 moles

Step 2: find the number of liters of ammonia

that is at STP 1 moles = 22.4 L

0.191 moles = ? L

by cross multiplication

={ (0.191 moles * 22.4 L) / 1 mole} = 4.28 L

The volume of 3.25 grams of ammonia is 4.28 L

Explanation:

Step 1: Data given

Mass of ammonia = 3.25 grams

Molar mass of ammonia = 17.03 g/mol

Step 2: Calculate moles ammonia

Moles NH3 = mass NH3 / molar mass NH3

Moles NH3 = 3.25 grams / 17.03 g/mol

Moles NH3 = 0.191 moles

Step 3: Calculate volume of NH3

1 mol = 22.4 L

0.191 moles = 22.4 * 0.191 = 4.28 L

The volume of 3.25 grams of ammonia is 4.28 L
