Question

How many moles are in 59.6 grams of caso3

Answer 1

0.496 mol

Step-by-step explanation:

To find the number of moles, you can use the formula:

`\[ \text{Number of moles} = \frac{\text{Mass}}{\text{Molar mass}} \]`

For
`\( \text{CaSO}_3 \)`, you need to find the molar mass of each element and add them up:

- Calcium (Ca):
`\(40.08 \, \text{g/mol}\)`

- Sulfur (S):
`\(32.07 \, \text{g/mol}\)`

- Oxygen (O):
`\(16.00 \, \text{g/mol}\) (there are three oxygen atoms, so \(16.00 * 3 = 48.00 \, \text{g/mol}\))`

Now, add these values:

`\[ \text{Molar mass of CaSO}_3 = 40.08 + 32.07 + 48.00 = 120.15 \, \text{g/mol} \]`

Now you can use the formula:

`\[ \text{Number of moles} = \frac{59.6 \, \text{g}}{120.15 \, \text{g/mol}} \]`

0.496 moles
