Agas has a volume of 750 ml at a pressure of 2.15 atm. what will the pressure be if the volume becomes 1.25 l?

1.29 atm.

Explanation:

To calculate the volume of a gas, we can use the general law of ideal gas: PV = nRT.

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.

If n and T are constant, and have two different values of V and P:

P₁V₁ = P₂V₂

P1 = 2.15 atm, V1 = 750 mL = 0.75 L.

P₂ = ??? atm, V₂ = 1.25 L.

∴ P₂ = P₁V₁/V₂ = (2.15 atm)(0.75 L)/(1.25 L) = 1.29 atm.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
