Question

Calculate the number of moles in 1.00 g of sucrose and of myristic acid. Enter your answers in the table below. (Hint: n = m/MW).

Answer 1

Answer: Number of moles of sucrose are 0.002 and number of moles of myristic acid are 0.004.

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

To calculate the moles, we use the equation:

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

1. sucrose
`(C_(12)H_(22)O_(11)`

`\text{Number of moles of sucrose}==(1.00g)/(342g/mol)=0.003moles`

2. myristic acid
`(C_(14)H_(28)O_(2)`

`\text{Number of moles of sucrose}==(1.00g)/(228g/mol)=0.004moles`

Thus number of moles of sucrose are 0.002 and number of moles of myristic acid are 0.004.
