Answer: The moles of melatonin are 0.000043

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

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

Given mass of melatonin = 0.01 g

Molar mass of melatonin (C_{13}H_{16}N_2O_2) = 232.28 g/mol

\text{Number of moles of melatonin}=\frac{0.01 g}{232.28g/mol}=0.000043mol

Thus the moles of melatonin in 0.01 g are 0.000043

What takes longer to melt a small quantity or a large quantity?
My name is Ann [436]

Answer:

A large quantity

Explanation:

A large quantity will take much longer to melt compared to a small quantity of the same matter.

The rate of melt of a substance is particularly a function of the nature of the substance and the amount of energy supplied to it.

If we assume that we are dealing with different quantities of the same substance, then the one that has more mass will melt faster because less energy would be required to change its state.

A large quantity of matter will take more time to melt.
