Answer:
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:
- 12*3 + 7*1 + 14 + 16*2 = 89 g/mol
Then we divide the sample mass by the molecular weight, to do the conversion:
- 1.0x10⁻² g ÷ 89 g/mol = 1.123x10⁻⁴ moles
