Answer:
0.22L
Explanation:
Given parameters:
Concentration of solution = 4.00M
Mass of lithium Bromide = 75g
Unknown:
Volume of water = ?
Solution:
Concentration in terms of the molarity is the number of moles of solute in a solution.
Molarity =
let us find the number of moles first;
Number of moles =
Molar mass of LiBr = 7 + 80 = 78g/mol
number of moles =
number of moles = 0.96moles
Volume of water = = 0.96/4 = 0.22L
