It's 20g, because 1000mg=1g
It's 20g. (1dag - 10grams)
Just divide to get the density, and compare. 20 / 10 = 2 g/cm3, 20/2 = 10 g/cm3, so the first is less dense.
Density is mass per unit volume. If 10 cm3 weighs 20g, the density is 2 g/cc.
there are 1000 g in 1 kg, 20g=.02kg hint, the prefix k means 1000
20/10 g/cm^3 =2 g/cm^3
20g
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
density = mass ÷ volume= 20 g ÷ 12 cm3≈ 1.67 g/cm3
20g
Density = (mass) / (volume) = 20/80 = 0.25 g/cc
The mass of lithium oxide (Li2O) is 8,o9 g.
