Calculate the molarity of a solution made with 15.7 g of NaCl in 100 ML solution

Data:

Mass of solute: 15.7 g of NaCl

volume of solution: 100ML of solution

Molar mass of solute: 58 g/mol

Explanation:

Convert 100ML to dm3:

100ML=0.1dm3

M=grams of solute/molar mass of solute*dm3 of solution

M=15.7/58*0.1

M=2.70M

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.

the answer is d.) potassium
