Question 641653
A 1% solution of hydrochloric acid is required for a procedure. A 5% solution is available. How much of the 5% will be required to make 500 mL of a 1% solution?
let x=amt of 5% required to make 500 mL of 1% solution
5%x=1%*500
.05x=5
x=5/.05
x=100
amt of 5% required to make 500 mL of 1% solution=100 mL
