The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
I think <span>3H2+N2==>2NH3</span>
When we are at STP conditions, we can use this conversion: 1 mol= 22.4 L
0.500 mol C₃H₈ (22.4 L/ 1 mol)= 11.2 L
In three hours and twenty minutes from 1:40 will be 5:00
