Answer: C
Step-by-step explanation:
5 significant figures but note that 0 is only non-significant when it begins a decimal its only significant when it's in between numbers or after a number
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
