The volume of 50 g. of a substance is 20cm^(3). If the density of water is 1g.cm^(-3), will the substance float or sink ?

Answer»

Solution :`"1. Density of substance"=("MASS")/("Volume")=(50g)/(120cm^(3))=2.58cm^(-3).`
`"2. Density of water"=1gcm^(-3).`
As the density of substance is greater than that water, so the substance will sink in water.
