Answer:
2.24g/
Step-by-step explanation:
mass of water is found by getting 5he extra mass the cylinder gained after adding
100g-80g=20g - mass of water
Density of water: 1g/cm³ that means that 20g water has a volume of 20cm³
1cm³=1ml; 20cm³=20ml
volume of stone is the extra height the water gained: 45ml-20ml =
25ml
mass of stone is the extra mass now earned:
156g-100g=56g
Density of stone=mass of stone÷divide by volume of stone
56g÷25ml=
2.24g/ml
