According to Henry's law, solubility is proportional to the external pressure. Since both cases in the problem have the same temperature, only the pressure varies from 1.0 atm to 2.5 atm. This means that just as the pressure is multiplied by a factor of 2.5, we can multiply the solubility by a factor of 2.5 as well. This gives us 0.041 g/L * 2.5 = 0.1025 g/L.
Answer:
the molarity of MgCl2 = 6.073 x 10^-2 M
Explanation:
Molarity = mole (n) divided by volume of solution (V) in liter = n/v
mole (n) = mass (m) divided by molecular mass (Mm) = m/Mm
n of MgCl2 = 2.891/95.3 = 0.03033 mole
v of solution = 500 ml = 0.500 L
Molarity = n/v = 0.03033/0.500 = 0.06066 M = 6.07 x 10^-2 M
