Wouldn't it have been better to show your work instead of leading us around to the back of the barn?
No you don't need the formula mas of MgCl2.6H2O.
If you can change pounds into liters you're a better chemist than I am. Pounds is a weight. L is a volume.
Change pounds to grams.
150 pounds x (453.59 g/pound) = ?
Then ?/1.69 = mL and convert to L.
I should point out here that no matter what answer you get it probably isn't right BECAUSE MgCl2.6H2O is a solid and the volume will depend upon how big the individual crystals are and how much space is between the solid particles. The size of the particles actually determines the volume of solids UNLESS it is a one piece solid.
Magnesium chloride hexahydrate has a density of 1.69 g/cm3. What is the volume in liters of 1.5 x10^2 pounds of MgCl2*6H2O?
yes D=m/v into V=m/d, Do I need to find the formula mass of Magnesium chloride hexahydrate and change pounds into liters? Divide the found numbers and I found my volume?
