It depends on the density of the material being sampled.
1.014 g/ml
0.961 g/mL
The mass of 1 mL of water is 1 g.
The density of the sample is about 2.14 g/mL
The estimated mass of 300 ml is about 300 grams. This can change based on the temperature and the density of the sample.
280 ml
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
5
1.6 g/ml
The second sample is 200/10 = 20 times as large. So its mass will be 20 times as great ie 20*20 grams = 400 grams.
