What is the molarity of a solution that contains 1.1 moles of lithium in 0.5 liters of solution?
2 answers:
0.5 litres contain 1.1 moles
therefore 1 litre will have= 1*1.1/0.5
molarity=2.2M
Answer:
The correct answer is 2.2 mol/L
Explanation:
Molarity of a solution is used to determine the concentration of that solution. It is mathematically expressed as
Molarity (M) = number of moles ÷ volume (in liters or dm³)
The unit for molarity is mol/L or mol/dm³ or M
From the question, number of moles is <u>1.1 moles</u> and the volume is <u>0.5 liters</u>.
Hence,
Molarity = 1.1 ÷ 0.5
Molarity = 2.2 mol/L
