if you have 2500cm^3 of nitrogen gas which of the following is the correct mass of nitrogen using significant figures
Thank you for the opportunity to help you with your question!
density of nitrogen 1.17X10^-3g/cm^3
mass = density * volume
mass = 1.17X10^-3g/cm^3 *2500cm3 = 1.77 *25 *10^-3*100 = 29.25 *10^-1 g
= 2.925 g
