Question

The approximate recommended daily dietary intake of the amino acid isoleucine, c6h13no2, is 2.00 g for a 100 kg adult. what is this requirement in moles?

Answer 1

Answer: The number of moles of isoleucine is 0.0152 moles.

Step-by-step explanation:

To calculate the number of moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

We are given:

Given mass of isoleucine = 2.00 g

Molar mass of isoleucine = 131.2 g/mol

Putting values in above equation, we get:

`\text{Moles of isoleucine}=(2.00g)/(131.2g/mol)=0.0152mol`

Hence, the number of moles of isoleucine is 0.0152 moles.

Answer 2

0.0152 mol. The recommended daily intake of isoleucine is 0.0152 mol.

The molar mass of C6H13NO2 is (72.06 + 13.10 + 14.01 + 32.00) g/mol

= 131.17 g/mol.

Moles = 2.00 g × (1 mol/131.17 g) = 0.0152 mol
