Agas has a volume of 50.0 cm3 at a temperature of -73°c. what volume would the gas occupy at a temperature of -123°c if the pressure stays constant? f 5.0 cm3 g 3.75 cm3 h 37.5 cm3 j 50.0 cm3

h. 37.5 cm³

Explanation:

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n  is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

(V₁T₂) = (V₂T₁).  

V₁ = 50.0 cm³, T₁ = -73°C + 273 = 200 K,

V₂ = ??? cm³, T₂ = -123°C + 273 = 150 K.

∴ V₂ = (V₁T₂)/(T₁) = (50.0 cm³)(150 K)/(200 K) = 37.5 cm³.

the answers would be

the first one and the second one
