Question

Calculate the milimoles threo-2,3-dibromo-3-phenylpropanoic acid. Molecular weight 308.0. Or at least explain what more I need to find millimoles.

Answer 1

Molecular weight of threo-2,3-dibromo-3-phenylpropanoic acid = 308 g/mol

So,

308 g of threo-2,3-dibromo-3-phenylpropanoic acid = 1 mole

Dividing both sides by 1000, we get;

(308/1000) g of threo-2,3-dibromo-3-phenylpropanoic acid = (1/1000) mole

0.308 g of threo-2,3-dibromo-3-phenylpropanoic acid = 1 millimole

1 g of threo-2,3-dibromo-3-phenylpropanoic acid = (1/0.308) millimole = 3.25 millimole

Now,

Mole = (Mass of the compound) / (Molecular weight)

Millimoles = [(Mass of the compound) / (Molecular weight) ] x 1000
