A 1.00 L of a solution is prepared by dissolving 125.6 g of NaF in it. What would be the molarity of this solution?

2.99 M

Explanation:

In order to solve this problem we need to keep in mind the definition of molarity:

In order to calculate the moles of solute, we convert 125.6 g of NaF into moles using its molar mass:

As the volume is already given, we can proceed to calculate the molarity:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
