Solution Summary

This solution provides assistance with the simple chemistry questions.

Solution Preview

a). Molar mass of glycine = 75.07 g/mol

(1.5 moles/Liter of glycine)*(1 Liter) = 1.5 moles glycine
(1.5 moles glycine)*(75.07 g/mol) = 112.61 grams of glycine

Dissolve 112.61 grams of glycine in 1 liter of water. You can change this mass to a volume through the density of glycine if you prefer.

b). Molar mass of glucose = 180.16 g/mol

(0.5 millimoles/Liter of glucose)*(1 Liter)*(1 mole / 1000 millimoles) = 0.0005 moles of glucose
(0.0005 moles glucose)*(180.16 gram/mol)*(1000 ...
