Question

how many milligrams of gas are formed if 10.0mL of 3.00% hydrogen peroxide solution decomposes? the density of the solution is 1.00g/mL. show work using dimensional analysis.

Answer 1

So, you that your hydrogen peroxide solution had a volume of 5 mL. The density of this solution was listed at

1.02 g/mL.

The weight by volume percent concentration,

%w/v, for a hydrogen peroxide solution that has that density is listed at 6.6%.
