Answer: The mass in grams of sodium carbonate is 34.3 g
Step-by-step 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 ml
moles of
=

Now put all the given values in the formula of molarity, we get


Therefore, the mass in grams of sodium carbonate is 34.3 g
