I'm stuck ~ looking for Chem whiz.

Here's the Q~

HNO3 decomposes ~ 4HNO3 = 4NO2 + 2H2O + O2
If we have only 4.0 X 10 (24th power) molecules of HNO3.

a.) HOw many moles
b.) How many grams of H2O will be produced?

I am looking not just for the answer, but how it is found (work).

CALCULATE IT YOURSELF!

a)How many moles of what?Incomplete question.....
But If youre talking about HNO3 I THINK it is...

{4.0 X 10 (24th power)}/{6.02X10 (23th power)}

b) {(The mole of HNO3) / 2} X 18

I'm not good at chemistry so that their is a very high probability that I'm wrong............at least that what I always do........
