Question

A 4.86 g piece of metal was placed in a graduated cylinder containing 15.5 mL of water. The water level rose to 17.3 mL. What is the density of the metal.

I need the steps of how to solve it to so I can use a formula to work out other problems.

Answer 1

Answer : The density of metal is, 2.7 g/ml

Solution : Given,

Mass of metal = 4.86 g

Volume of initial water = 15.5 ml

Volume of rose water = 17.3 ml

First we have to calculate the volume of metal.

Volume of metal =  volume of rose water - volume of initial water

Volume of metal = 17.3 - 15.5 = 1.8 ml

Now we have to calculate the density of metal.

Formula used :

$Density=\frac{Mass}{Volume}$

Now put all the given values in this formula, we get the density of metal.

$Density=\frac{4.86g}{1.8ml}=2.7g/ml$

Therefore, the density of metal is, 2.7 g/ml
