2 mole (N2H5)2C3H4O4 (14 mole H/1 mole N2H5)2C3H4O4)
= 28 moles hydrogen
======I am not adding that molar mass, but....
0.740 mole (N2H5)2C3H4O4 (Molar mass (N2H5)2C3H4O4/ 1 mole (N2H5)2C3H4O4)
=
How many moles of H are there in two moles of (N2H5)2C3H4O4? How many grams of (N2H5)2C3H4O4 are in 0.740 moles?
