Asample of 3.0 mols of hydrogren gas has a volume of 75ml. 1.5 mols of hydrogen is added if the pressure and temperature remains constant ,calculate the final volume of the gas?

37.5 mL.

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.

(V₁n₂) = (V₂n₁)

Knowing that:

V₁  =  75 mL, n₁ = 3.0 mol,

V₂  =  ??? mL, n₂ = 1.5 mol.

(V₁n₂) = (V₂n₁)

∴ V₂ = (V₁n₂)/n₁ = (75 mL)(1.5 mol)/(3.0 mol) = 37.5 mL.

your parents i think this could be it

idk i’m struggling too
