Balancing Equations: 2H2 + O2 -> 2H2O - 180g of Water Produced

[draotic]

Homework Statement

if 20.0 g of dihydrogen is reacted with 20.0 g of dioxygen , how many grams of water is produced?

Homework Equations

The Attempt at a Solution

balancing
2H2 + O2 = 2H20
now 2 mole h2 gives 2mole H2O
so 20/2 moles of H2 will give 10 moles H2O
10 x 18 = 180 g
...
am i right?

You start with 20g + 20g = 40g of reactants, is it possible to produce 180g of water?

the nhow do i do it?

What if you start calculations with oxygen?

Start by finding out the limiting reagent. :)
