The total weight of the cylinder, water, and aluminum solid is 27.586g. What will the final volume of the water be in the graduated cylinder? density of aluminum= 2.7 g/mL

try using this equation mi x vi = mf x vf

in translation mass initial * volume initial equals to mass final * volume final. just plug in the numbers.
