if a sample of an aerogel has a volume of 87.3 cm and a density of 0.250 gem what is the aerogel's mass?

Density = mass/volume therefore mass = density * volume

Just do Density= Mass / Volume

ah...science, my hated subject... XD math isnt too bad.
formula: density= mass divided by volume
you know the volume and density. just substitute.
0.250=mass/87.3
multiply 87.3 on both sides to get the mass. too lazy to do math.
=] enjoy!

if density=mass/volume, so:
density=0.250g/cm³
volume=87 cm³
mass=density*volume=0.250*87=21.75g
