Answer:
A standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
All the data is given in the question and these are as follows:-
Moles - 0.75
Na - 6.022*10^{23
The formula we are using to find the molecules is as follows:-
n = \frac{molecule}{Na}n=
Na
molecule
After, putting the value and solving it. we will get
0.75 * 6.022*10^2^3 = 4.5165*10^{23
