Answer:
Mass = 6.706 g
Explanation:
Given data:
Mass of lithium hydroxide = ?
Volume of lithium hydroxide = 450 mL (450/1000 = 0.450 L)
Molarity of lithium hydroxide = 0.55 M
Solution:
Formula:
Molarity = number of moles / volume in L
0.55 M = number of moles / 0.450 L
Number of moles = 0.55 M × 0.450 L
Number of moles = 0.25 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.25 mol × 23.95 g/mol
Mass = 6.706 g
