Answer: 429 grams of 
should be added to 1.3 L of water to prepare 2.0 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n = moles of solute = 
= volume of solution in Liters
Now put all the given values in the formula of molarity, we get
