1 N204(l) + 2 N2H4(l) --> 3 N2(g) + 4 H2O(g) If you start with: 5.0 x 10^4 hydrazine (N2H4) "in the tank": 1) How many moles of nitrogen can be created (assuming 100% yield)? 2) How many moles of water can be produced? 2) What mass of dinitrogen tetroxide...

How many molecules are in 15g CH4? How do you figure this out?

How many moles of carbon monoxide gas are produced when 2.88 moles of SnO2(s) react with excess carbon according to the equation below? SnO2(s) + 2C(s) --> Sn(s) + 2CO(g) How do you figure all of this out?

Consider the following reaction: H2O(l) + 3NO2(g) --> 2HNO3(l) + NO(g) What volume of NO (in L) is produced starting from 1.80 g of water and 11.5 g of NO2 at 300 K and 1 atm? (use R = 0.0821 L atm/mol K). I am completely confused :(

sorrry. in grams.
