Question

Determine the number of KNO3 molecules in 0.750mol KNO3

Answer 1

The number of KNO3 molecules in 0.750 mol of KNO3 would be 4.52 x  $10^{23}$ molecules

Number of molecules

The number of molecules of a substance is defined by Avogadro's constant, such that:

1 mole = 6.022 x $10^{23}$ molecules

In this case, the number of mole is 0.750

Thus, the number of molecules in 0.750 moles of KNO3 can be calculated as:

        0.750 x 6.022 x $10^{23}$ = 4.52 x  $10^{23}$ molecules
