Question

What is the volume of 2.75 mol of a gas at STP?

1) 61.6 L
2) 22.4 L
3) 8.15 L
4) 2.75 L

Answer 1

The volume of 2.75 moles of a gas at STP is calculated by multiplying the number of moles by the molar volume of 22.4 L/mol, resulting in a volume of 61.6 L. The correct option is 1).

Step-by-step explanation:

The volume of 2.75 moles of a gas at Standard Temperature and Pressure (STP) can be calculated using the concept of molar volume. At STP, 1 mole of any ideal gas occupies 22.4 liters (L) of volume. To find the volume of 2.75 moles, you simply multiply the number of moles by the molar volume:

22.4 L/mol × 2.75 mol = 61.6 L

Therefore, the volume of 2.75 moles of a gas at STP is 61.6 liters. The correct answer is 1) 61.6 L.
