How many grams of Carbon dioxide (CO2) are needed to create a 40M
solution in 150ml of solution?

a) 264
b) 0.14
c) 26.4
d) 0.27

264 grams of Carbon dioxide (CO2) are needed to create a 40M  solution in 150ml of solution.

Explanation:

Given :

molarity of the solution = 40M

Volume of the solution = 150ml or 0.15 litres after dividing it by 1000

compound is carbon dioxide

atomic mass of CO2 = 44.01 gram/mole

mass of CO2 = ?

moles of Co2 =?

the relation between grams and molarity is given by:

number of moles =  equation 1

molarity is given by :

Molarity =  equation 2

 Putting the value of number of moles in equation 2

molarity =

mass = molarity x atomic mass x volume

mass = 40 x 0.15 x 44.01

         = 264 grams

264 grams is the mass of carbon dioxide required to make a solution of 40 M in 150 ml of solution.
