Back (Answer)
➢20 degrees and 1 atmosphere
#3
Front (Question)
What is the equation for the number of moles of gas?
Back (Answer)
➢ Volume of gas (dm^3)/24 dm^3
#4
Front (Question)
One make of car has an air- bag that is inflated by 70.0g of nitrogen, N2 when activated. What volume would the nitrogen gas occupy at room temperature?
Back (Answer)
➢ Find moles of nitrogen by mass / relative formula mass ➢ 70/14x2 = 2.5mol ➢ Then use the number of moles in a gas formula ➢ 2.5 = volume of gas / 24 ➢ Volume of gas = 60dm^3
#5
