Calculate the mass of CO2 dissolved in 2.480L of water at 350.7torr if henry's law constant is 0.03100

To calculate the mass of CO2 dissolved in water using Henry's Law, we need to use the following formula:

Mass of CO2 = Henry's Law constant * Pressure * Volume

Given:
Henry's Law constant (k) = 0.03100
Pressure (P) = 350.7 torr
Volume (V) = 2.480 L

First, let's convert the pressure to atmospheres since the Henry's Law constant is typically given for atmospheric pressure.

1 atm = 760 torr
So, the pressure in atmospheres is:
P = 350.7 torr / 760 torr/atm = 0.460921 atm

Now, we can calculate the mass of CO2 dissolved in water:
Mass of CO2 = 0.03100 * 0.460921 atm * 2.480 L

Multiply the values together:
Mass of CO2 = 0.072072 g

Therefore, the mass of CO2 dissolved in 2.480 L of water at 350.7 torr is approximately 0.072072 grams.
