# A student dissolves 106 g of Na_2CO_3 in enough water to make a 6.00 L solution. What is the molarity of the solution?

Mar 4, 2016

$0.1667 M$

#### Explanation:

1. Take the formula mass of $N {a}_{2} C {O}_{3}$
2. Find the number of moles by dividing the amount of $N {a}_{2} C {O}_{3}$ as provided in the problem by its formulas mass;
3. Compute the Molarity (M) using the formula;
M=number of mol/L solution
4. Make sure to cancel out units leaving only the desired unit
5. Per calculation, M=0.1667 mol/L
