Expressing Concentration Of Solutions

Given:

Mass of NaOH = 10 g
Molar mass of NaOH = 40 g/mol
Volume of solution = 250 mL = 0.250 L

Step 1: Calculate the number of moles of NaOH

Moles of NaOH = $%5Cfrac%7B%5Ctext%7BMass%7D%7D%7B%5Ctext%7BMolar%20Mass%7D%7D%20%3D%20%5Cfrac%7B10%20%5C%2C%20%5Ctext%7Bg%7D%7D%7B40%20%5C%2C%20%5Ctext%7Bg%2Fmol%7D%7D%20%3D%200.25%20%5C%2C%20%5Ctext%7Bmol%7D%3C%2Fp%3E%3Ch3%3EStep%202%3A%20Calculate%20the%20molarity%20of%20the%20solution%3C%2Fh3%3E%3Cp%3EMolarity%20%5C(%20M$ = $%5Cfrac%7B%5Ctext%7Bmoles%20of%20solute%7D%7D%7B%5Ctext%7Bvolume%20of%20solution%20in%20liters%7D%7D$
