What is mole of 0.49 grams of So4 ion

1 answer

To determine the number of moles of 0.49 grams of SO4 ion, we must first calculate the molar mass of the SO4 ion. The molar mass of SO4 ion is calculated as follows:

Sulfur (S) has a molar mass of 32.06 g/mol
Oxygen (O) has a molar mass of 16.00 g/mol

The total molar mass of SO4 ion is:
32.06 g/mol (S) + 4(16.00 g/mol) (O) = 96.06 g/mol

Now we can calculate the number of moles of 0.49 grams of SO4 ion using the formula:

Number of moles = Mass / Molar mass
Number of moles = 0.49 g / 96.06 g/mol
Number of moles ≈ 0.0051 moles

Therefore, 0.49 grams of SO4 ion is approximately equal to 0.0051 moles.
