Answer 2

Answer:

Step-by-step explanation:

OMG IVE LEARNY THIS YESTERDAYYY!!!

Ok, so what you need to do first is to always remember the formula for finding the density which is

Density= mass÷ volume.

The question states the mass of the rock is 16g

And to find the volume of the rock is: final volume subtracting the initial volume

= 75ml - 50ml

=20 ml cubed

Hence:

Density=16g÷25ml

Oh I forgot in the picture, it's written that ml cubed is the same as centimetres cubed.

Back on to what I was saying before

Density = 16g÷25cm cubed

=0.64g/cm^3,if you want to convert the g to kg and cm to m because the SI unit of mass is kg and volume is metres

To convert 0.64g/cm^3 you × 1000 which is

=640kg/m^3

Adiosss
