If .19 moles of sodium carbonate are dissolved in enough water to make .400 L of solution, what is the molarity?

=0.475M

Explanation:

Molarity=(moles of solute))/(litres of solution)

So, molarity in this question:

=(0.19 moles of sodium carbonate)/(0.4 L of solution)

=0.475M

~Hope this helps:)

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
