Question

Helpp!

how many milliliters of a 10% hydrogen peroxide solution and how many milliliters of a 2% hydrogen peroxide solution should be mixed to obtain 500 mL of a 4% hydrogen peroxide solution?

Answer 1

i will answer it

Answer 2

Equation:
hydro + hydro = hydro
0.02x + 0.10(500-x) = 0.04*500
------------------
2x + 10*500 - 10x = 4*500
----
-8x = -6*500
----
x = (3/4)500
x = 3*125 = 375 ml (amt. of 2% solution needed)
500-x = 125 ml (amt. of 10% solution needed)
