How many moles of neon occupy a volume of 14.3 l at stp? how many moles of neon occupy a volume of 14.3 l at stp? 1.57 moles 0.638 moles 36.7 moles 32.0 moles 6.45 moles?

Answer 1

The number of neon moles that occupy a volume of 14.3 l at STP is calculated as follows

At STP 1 mole = 22.4 liters

what about 14.3 liters

by cross multiplication
= (1 mole x 14.3 l)/22.4 l =0.638 moles of neon
