Question

Calculate the moles of argon gas at STP in 33 L. Round answer to 2 significant figures.

Answer 1

1.5 mol

Step-by-step explanation:

Step 1: Given data

• Volume of argon gas: 33 L

• Standard temperature: 273.15 K

• Standard pressure: 1 atm

Step 2: Calculate the moles corresponding to 33 L of argon at standard temperature and pressure (STP)

At STP, 1 mole of argon gas occupies 22.4 L.

33 L × 1 mol/22.4 L = 1.5 mol
