At 300 K, 40 mL of `O_3,` (g) dissolves in 100 g of water at 1.0 atm. What mass of ozone dissolves in 400 g of water at a pressure of 4.0 atm at 300 K is nearly

Options

A. 0.1g
B. 1.25g
C. 0.5g
D. 5g

Answer

D

Explanation

40mL `O_(3)` dissolves in 100g water at 300K and 1 atm
`40 xx 4 mL O_(3)` dissolve in 400g water at 300K and 1 atm
`because m prop P` so `(40 xx 4) xx 4mL O_(3)` dissolve in 400g water at 300K and 4 atm
`n_(O_(2))` dissolved `=(4xx 640 xx 10^(-3))/(0.0821 xx 300)= 0.1` or mass of `O_(3)=5g`
