Chapter 3: Q.20E (page 129)

The approximate minimum daily dietary requirement of the amino acid leucine, C6H13NO2, is 1.1 g. What is this requirement in moles?

Short Answer

Expert verified

Number of moles of leucine C6H13NO2 = 0.00839 mol

Step by step solution

01

Determine molecular weight of C6H13NO2

C6H13NO2

Mass of the compound = 1.1 g

Molecular weight of C6H13NO2 = 6 x 12 + 13 x 1+ 14 + 2 x 16 = 131 g/mol

02

Determine number of moles of C6H13NO2 present

Number of moles = (Weight in grams/Molecular weight)

By using the above formula, we can calculate the number of moles

= Number of moles = (1.1gm/ 0.00839 mol)

= 131 g/mol
