Question

A 105g slab of metal is dropped into a cylinder which has 69.9ml of water in it. The water goes up to 83.3ml with the metal slab in it. What is the density?

Answer 1

Answer: The density of metal is 7.83 g/ml

Solution :

Given, Mass of metal = 105 g

First we have to calculate the volume of sand

Volume of metal = volume of water displaced= (83.3-69.9)=13.4 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.

$Density=\frac{105g}{13.4ml}=7.83g/ml$

Therefore, the density of metal is  7.83 g/ml    

Answer 2

The density is 19.4 g/ml the units could also be 19.4 g/cm^3
