To calculate the number of moles in 7.20g of H\(_2\)O, we first need to find the molar mass of H\(_2\)O. The molar mass is the sum of the atomic masses of all the atoms in the compound. In this case, H\(_2\)O consists of two hydrogen atoms (H) and one oxygen atom (O).

The atomic mass of hydrogen is approximately 1g/mol, and the atomic mass of oxygen is approximately 16g/mol. So, the molar mass of H\(_2\)O is:

Now, we can use the formula for calculating the number of moles:

Substitute the given mass (7.20g) and the molar mass of H\(_2\)O (18g/mol) into the formula:

Perform the calculation:

So, there are0.40 moles of H\(_2\)O in 7.20g of the compound, which corresponds toOption D.

Correct Answer: D. 2

Correct Answer: B. 4.69kg
