7.226 * 10^23 molecules.
Explanation: A compound is a substance that is made by two or more atoms from different elements. A mole of a compound contains a number of molecules equivalent to Avogadro's number, 6.022 * 10^23. That is, one mole of a compound contains 6.022 * 10^23 molecules.
In this case we are given;
Number of moles of H₂O as 1.2 moles
But, 1 mole of H₂O contains 6.022 * 10^23 molecules.
We are required to calculate the number of molecules present;
To calculate the number of molecules we are going to multiply the number of molecules in one mole by the number of moles. Therefore;
Number of molecules = 1.2 moles * 6.022 * 10^23 molecules/mole
= 7.226 * 10^23 molecules.
Thus, 1.2 moles of water contains 7.226 * 10^23 molecules.
