The molecular weight of a gas is ________ g/mol if 6.7 g of the gas occupies 6.3 L at STP. A)24 B)3.6 × 10³ C)27 D)3.0 × 10² E)1.8 × 10^-2

Question

Quizplus · Accepted Answer

At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L. The molecular weight (M) can be calculated using the formula: M = (mass in grams / volume in liters) * 22.4 L/mol. Substituting the given values: M = (6.7 g / 6.3 L) * 22.4 L/mol = 24 g/mol.

The Molecular Weight of a Gas Is ________ G/mol If
