Question

The diagram shows measuring instrument A. It contains 50cm of water th stone has been carefully lowered into the water
a)what is the total volume in cm of the contents of A?
b)calculate the volume in cm of the stone
c) if the mass of the stone is 36g .find its density

Answer 1

Answer:

The volume of the stone is equal to the volume of the water increased in the measuring cylinder.

The volume of the stone is calculated from the formula Volume =Mass/Density.

In this case, the Mass = 12 g and Density = 3gcm

.

Volume = 12/3 = 4cm

.

The actual volume of liquid in the measuring cylinder is 20cm

.

So, the increase in volume will show a new reading of 20cm

+4cm

=24cm

.

Hence, the new reading on the measuring cylinder is 24cm
