1. for dry air at 1. atm pressure, the densities at –50°c, 0°c, and 69°c are 1.5826 g dm–3 , 1.2929 g dm–3, and 1.0322 g dm–3, respectively. a) assume a sample of mass 1000 g, and calculate the volume at each temperature. b) from these data, and assuming that air obeys charles’s law, determine a value for th

Answer :

(a) The value of volume of air at temperature are respectively.

Explanation :

(a) The formula used for density is:

or,

Now we have to calculate the volume at each temperature.

The mass of sample = 1000 g

At temperature :

Density =

At temperature :

Density =

At temperature :

Density =

your answer would be “dry”
