The density of a solution of ferric chloride is 1.058g/cc, and it is 7.00 percent by mass. What volume of the soltion (in mL) do you need to supply 34.0g of ferric chloride?

2. Relevant equations

D=m/v

3. The attempt at a solution

Not sure where to begin. I dont understand the statement, " and it is 7 percent by mass". Does this mean i ned to multiply 34*0.07? then just calculate the volume by rearranging the density formula?
