1. How many moles of solute are present in each of the following solutions? A) 275 mL of 2.50 M LiCl B) 25.0 mL of 0.600 M Na2SO42. How many mL of 0.0988 M HCl are needed to titrate 35.7 mL of 2.00 M NaOH?
3. How many mL of 0.0988 M HCl are needed to neautrilize 0.750 g of NaOH?
4. Calculate the mL of water that must be added to 300.0 mL of a 1.50 M HCl solution to make a dilute solution of 0.580 M HCl? Assume the volumes are additive
5. Calculate the volume of 0.125 M H2SO4 required to completely neautrilize 25.0 mL of 0.140 M NaOH solution. H2SO4 (aq) + NaOH (aq) -> Na2SO4 (aq) + H2O (L) 1. How many moles of solute are present in each of the following solutions? A) 275 mL of 2.50 M LiCl B) 25.0 mL of 0.600 M Na2SO4

Explanation / Answer
Molarity = no. Of moles of solute in 1 litre of solution
M = n/ V: n= M x V (litre)
A) 275 mL of 2.50 M LiCl
No. Of moles of LiCl = 2.5 M x 0.275 L = 0.6875 moles
B) 25.0 mL of 0.600 M Na2SO4
No. Of moles of Na2SO4 = 0.025L x 0.600 M = 0.015 moles
