Question

To make a 5.30 kg, 4.12 % (by mass) H₂O₂ solution, what is the amount (in g) of hydrogen peroxide (H₂O₂) needed?

science chemistry

Answer 1

Answer #1

% (w/w) H₂O₂ solution =

Given, %(w/w) = 4.12

Weight of solution = 5.30 kg = 5.301000 g

Then, = 4.12

Or, weight of H₂O₂ = (4.12*5.30*1000/100) = 218.36 g.

So, amount of Hydrogen peroxide needed = 218.36 g.
