Calculate how many moles of glycine are in a 160.0-g sample of glycine. express your answer using four significant figures.

TO calculate for the number of moles, all we have to do is to take the ratio of mass over molar mass.

Glycine has a molecular formula of C2H5NO2 with a molar mass of 75.07 g/mol.

Therefore:

number of moles = 160 g / (75.07 g / mol)

number of moles = 2.13 moles

i think so it’s will be b yes i believe its

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
