Asked by Carli
2H20(l) = 2H2 (g) +O2 (g)
For the above, if 1.50 mg of water is decomposed, what mass of hydrogen is procduced? (1 Mg=10^6g=1 metric ton)?
What is the answer and what is the best way to solve this?

I am confused because you have used mg and Mg interchangeably. Here is the general procedure.
1. You have the balanced equation.
2. Convert grams water to moles. mols = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles H2O to moles H2.
4. Now convert moles H2 to grams. g = moles x molar mass.

I see your post piggy backed onto Jill's question. Repost here if you still have trouble.

Thanks for the info.
I came up with 0.1678475161 and rounded it to .17 mg H2. Am I on the right track and did I include the correct amount sig figs?
