The solubility of co in water at 0c and 1 atm co pressure is 0. 0354 mg of co in 1 ml of water. Calculate the moalrity of aqueso
Dmitriy789 [7]

From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.

<h3>What is molarity?</h3>

The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where

  • C = concentration
  • k = constant
  • p = pressure

C =  0. 0354 * 10^-3 g/28 g/mol × 1000/1 L

C = 0.0013 M

k = C/p = 0.0013 M/1 atm

k = 0.0013 Matm-1

Now;

C =  0.0013 Matm-1 *  2 atm

C= 0.0026 M
