Question

carbon dioxide occupy at standard temperature and pressure? (put in correct significant figures)

Answer 1

Both pieces of data use 3 significant figures, so the answer must have 3 significant figures too.

Also, p = m/V, density is mass divided by volume. So V = m/p, volume is mass divided by density. Therefore

V = (6.30 kg)/(1.98 kg/m³) = 3.18 m³.
