Silver has a density of 10.5 g cm3 and gold has a density of 19.3 g/cm3. which would have the greater mass, 5cm^3 of silver or 5cm^3 of gold?

Some one who has an idea of variation would solve this without a problem ...

Silver has density = 10.5g/cm³ and a volume of 5cm³

Gold has a density = 19.3g/cm³ and volume of 5cm³

If you observe the volumes are the same ...

Density = mass/volume

Mass = density * volume

Since the volume is constant, the material with the greater density will have the greater mass and that's gold ...

You might want to test

For gold mass = 19.3*5 = 96.5g

For silver mass = 10. 5 * 5 = 52.5g

96.5g>52.5g so gold has a higher mass ...
