What volume, in liters, will 6.32 × 10^2 of air occupy if the density of air is 1.29 g/l? express your answer in scientific notation.

4.90× 10^2 L

I am guessing that the mass of the air is 6.32 × 10^2 g. Then,

Volume = 6.32 × 10^2 g × (1 L/1.29 g) = 4.90× 10^2 L

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
