Answer:
0.205M
Step-by-step explanation:
Molarity is an unit of concentration used in chemistry defined as the ratio between moles of solute (In this case, LiF) and liters of solution.
To solve this question, we must find the moles of LiF and the liters of the solution:
Moles LiF -Molar mass: 25.939g/mol-:
2.39g * (1mol / 25.939g) = 0.0921moles
Liters solution:
450mL * (1L / 1000mL) = 0.450L
Molarity is:
0.0921 moles / 0.450L =
0.205M
