Question

a 340.4 ml sample of solution contains 27.4 g of cacl2. calcuate the molar concentration of calcium ion in this solution.

this is what i did
27.4(110.98) =.247mol
.247mol/34.4L=.726Mcacl2
is this correct?

Answer 1

ARRRRGGGGG.

moles=27.4g/(110.98) =.247mol
molarity=.247/.3404liters=.726Moles/liter

Answer 2

whats arrgg mean?
