10% solution
HI
I need to make 10% formic acid (my formic acid has a 88% purity)
i'm confused as to how to do this. let's use 100 mL to make it easier to calculate.
Do I:
A. 10 mL formic acid + 90 mL H20
or
B. 10 mL formic + 100 mL H2O?
When do I use A and when do I use B to calculate?
I was making a 0.1% Formic acid in water 1 L solution, I used calculation B to make the solution. 1.14 mL of formic acid + 1000mL H2O.
