You need 5.0 grams of LiOH for a reaction, but all you have on hand is a 2.75 M aqueous LiOH solution. What volume of the soluti on should you add to the reaction mixture to supply the 5.0 g of LiOH
1 answer:
Answer:
75.9mL of 2.75M LiOH solution
Explanation:
Molarity is an unit of concentration defined as the ratio between moles and liters. And the molar mass of LiOH is 23.95g/mol. With this information, it is possible to know the volume of solution you should add to supply 5.0g, thus:
5.0g LiOH × (1mol / 23,95g) × (1L / 2.75mol) × (1000mL / 1L) = <em>75.9mL of 2.75M LiOH solution</em>
