Question

Convert 34 dm^3 of ammonia gas to moles

Answer 1

Solution:

ammonia gas = NH₃

34 dm³ = 34 L (since 1 dm³ = 1 L)

At STP (Standard Temperature and Pressure), one mole of any gas occupies a volume of 22.4 L.

Thus 34 L of NH₃ corresponds to:

(34 L) × (1 mol / 22.4 L) = 1.5178 mol NH₃ = 1.52 mol NH₃

Answer: 1.52 mol NH₃
