Question

How much iodine (I2), in grams, should be added to water to produce 2.5L of solution with a molarity of 0.56M?

Answer 1

Molarity=Moles of solute/Volume of solution in L

So

• 0.56M=moles/2.5L
• moles=0.56(2.5)
• moles of Iodine=1.4mol

Mads of Iodine

• Moles(Molar mass)
• 1.4(126.9)
• 177.66g
