Answer: $3.5\times 10^{-4}$

Explanation:

To calculate the moles, we use the equation:

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

Given mass of theobromine $(C_7H_8N_4O_2)$ = 0.064 g

Molar mass of theobromine $(C_7H_8N_4O_2)=12\times 7+1\times 8+14\times 4+16\times 2=180 g$

$\text{Number of moles}=\frac{0.064g}{180g/mol}=3.5\times 10^{-4}moles$
