which of the following molecules are chiral? i. cis-1,3-dibromocyclohexane ii. 1-bromo-1-methylcyclohexane iii. trans-1-bromo-3-methylcyclohexane iv. cis-1-bromo-3-methylcyclohexane

2.5 L.

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.

P₁V₁ = P₂V₂

P₁ = 5.0 atm, V₁ = 3.5 L.

P₂ = 7.0 atm, V₂ = ??? L.

∴ V₂ = P₁V₁/P₂ = (5.0 atm)(3.5 L)/(7.0 atm) = 2.5 L.
