An aqueous solution of copper (I) chloride is 15.7% by mass copper (I) chloride. Copper (I) is 35.8% by mass chlorine. If the solution has a density of 1.045 g/cm³, how many gallons of solution contain 2.3 kg of copper?
Trying to help my son study.
solve for mass of copper(I) chloride from that.
Now, consider density.
density=masswater/volume + masscopperchloride/volume
from that you know everything except volume. Solve for volume, in cm^3
now, convert cm^3 to gallons. Watch units carefully here, giving the copper content is kg, density in g... Work it in g/cm^3 until the last conversion to gallons.
