Answer:
3 g/mL
Explanation:
Density is mass divided by volume (g/mL).
Mass of rock = 12.5
Volume of rock = 24-20 = 4mL
Density of rock = 12.5g/ 4mL = 3.125 g/mL
Round to the lowest number of significant figures which is 1 to get 3 g/mL
Low pressure and low temperature as the lower these are, the lower the kinetic energy is.
Three. There’s 2 atoms in hydrogen and there’s 1 atom in oxygen.
