How many moles are in 16.94g of water?

To determine the number of moles in 16.94g of water, we need to use the formula:

moles = mass / molar mass

First, we need to find the molar mass of water (H2O). The molar mass of hydrogen (H) is approximately 1g/mol, and the molar mass of oxygen (O) is approximately 16g/mol. Since water has two hydrogen atoms and one oxygen atom, the molar mass of water is:

(2 * 1g/mol) + (1 * 16g/mol) = 18g/mol

Now we can calculate the number of moles:

moles = 16.94g / 18g/mol

moles ≈ 0.94 mol

Therefore, there are approximately 0.94 moles in 16.94g of water.
