Question

2NaOH+2Al+2H2O --> 2NaAlO2+3H2

here is the reaction. If i am trying to find the mass of hydrogen produced and i am trying to convert .95 moles Al to moles H, which number from the reaction do I use for H when converting from moles to moles? Do I 6 because that's the number that balances the Hydrogen, or is that wrong?

Answer 1

To convert from .95 mol Al to mol H, you would use the coefficients in the balanced equation.

Here's an example of a stoichiometry problem:
