A 1.0 x 102- gram sample is found to be pure alanine, an amino acid found in proteins. How many moles of alanine are in the sample

1.123x10⁻⁴ moles of alanine

Explanation:

In order to convert grams of alanine into moles, we need to know its molecular weight:

The formula for alanine is C₃H₇NO₂, meaning its molecular weight would be:

Then we divide the sample mass by the molecular weight, to do the conversion:

2b2t

explanation:

2b2t
