2 g of glycine (C2H5NO2) are dissolved in water to a total volume of 3 L. What is the concentration of the glycine solution in M? Round answers to two significant figures.

Answer 1

Molarity=mass/MW / 3
= 2/(3*75) check my molmass.

Answer 2

Molarity = (mass/Molarmass)/3
= (2/75)/3
= 0.0267/3
= 0.0089
= 0.01 M
