Answer:
5.06 M LiCl
Explanation:
To find the new molarity of the solution, you need to (1) find the amount of moles LiCl (via the molarity equation using the original molarity and volume) and then (2) calculate the new molarity (via the molarity equation using the new volume and old moles). The final answer should have 3 sig figs to match the given values.
Molarity (M) = moles / volume (L)
<u>Step (1)</u>
381 mL / 1,000 = 0.381 L
Molarity = moles / volume
9.96 M = moles / 0.381 L
(9.96 M) x (0.381 L) = moles
3.79 = moles
<u>Step (2)</u>
750 mL / 1,000 = 0.750 L
Molarity = moles / volume
Molarity = 3.79 moles / 0.750 L
Molarity = 5.06 M
