Help a brother out!!! please!!!Nitroglycerin, C3H5N3O9 decomposes to form N2,CO2,H2O, and O2

4(C3H5N3O9)-> 6N2+12O2+10H20+O2

a)How many grams of water would be produced if 75g of nitroglycerin decompose?
b)The creation of 3.89 moles of C02 would require how many grams of nitroglycerin
TY!

Correction!! in the question its **12CO2**
Nitroglycerin = NG
mols NG = grams/molar mass = ?
Use the coefficients in the balanced equation to convert mols NG to mols H2O.
Now convert mols H2O to grams. g = mols x molar mass

b.
Convert 3.89 mols CO2 to mols NG using the coefficients.
Then g NG = mols NG x molar mass NG
