If a gas at 315 k has a volume of 1.50 l , what is the volume of the gas when the temperature is reduced to 215 k

1.02 L.

Explanation:

For this problem, you have to apply one of the gas laws --Charles' Law. It is as follows: V1/T1 = V2/T2. Substituting the values in and using sig figs, we get 1.02 L.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
