A sample of gaseous neon has a volume of 68.2 L at STP.How many moles of neon are in the sample? A) 0.328 mol B) 3.04 mol C) 68.2 mol D) 1530 mol E) 4.11 × 10²⁵ mol

Question

Quizplus · Accepted Answer

At Standard Temperature and Pressure (STP), 1 mole of any gas occupies 22.4 liters. To find the number of moles of neon in 68.2 liters, divide the volume of the gas by the volume occupied by one mole of gas at STP: 68.2 L / 22.4 L/mol = 3.04 mol.
