To calculate the number of moles of tin atoms in a pure tin cup, you can use the formula:
[ \text{moles of tin} = \frac{\text{mass of tin (g)}}{\text{molar mass of tin (g/mol)}} ]
The molar mass of tin is approximately 118.71 g/mol. Simply divide the mass of your tin cup by this value to find the number of moles.

How many moles of water are on 72.08g of H2O?
To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol). Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.
