Question

An object of mass 36.4 g was placed in 52.7 ml water. D= 2.82g/ml. Find Volume of object? HOW?

Answer 1

The formula for density is as follows:

Density = mass / volume

Therefore, Volume = mass / density

The mass and the density of the object are given in the problem so its density can be calculated directly using the formula.

Volume = 36.4g / 2.82g/mL

Volume of object = 12.9 mL

Answer 2

Measure the  volume of the water and object together, and subtract 52.7.    It is pretty easy if you just use a large graduated cylinder.

Edit:   Since D=M/V      then V=M/D     so the volume is 36.4g divided by 2.82 g/ml    or approx. 12.908 ml
