Can someone please show me the steps for this problem? thank you!

If 7 milliliters of water for injection were added to lyophilized protein powder, the resulting concentration was 3,500,000 units/mL. What is the volume of the dry powder if the protein amount in the vial was 35,000,000 units?

3500000u ___ 1 ml
35000000u ___ x ml (total volum)
x=10 ml
10-7(diluent)=3ml powder
please feedback if that is right .
