Franco Atkinson · Answer 1

The number of moles of a gas added to the container is calculated as follows

intial concentration = 7.51 moles

final moles - initial moles

final moles icalculation

3.10L = 7.51 moles

11.9L = ? moles

by cross multiplication

11.9 L x 7.51 moles / 3.10 L = 28.83 moles

the number of moles added is therefore = 28.83 moles - 7.51 moles = 21.32 moles
