Asample of a substance has a mass of 78.9 g and a volume of 84.3 cm3 what is the density?

d = 0.936 g/cm3

Explanation:

m = 78.9 g

V = 84.3 cm3

m = V × d

=> d = m/V = 78.9/84.3 = 0.936 g/cm3

Take the atomic mass in grams and the number of atoms in the sulfur molecule and multiply: so 8 x 32.065 grams = 256.52 grams. That iDVD the number of grams in one mole of sulfur. In each mole of anything there are Avogadro's number (6.022x10^23) of molecules.

Hope this helps
