1. Find the molar mass of platinum:
* The molar mass of platinum (Pt) is 195.084 g/mol. This means that one mole of platinum weighs 195.084 grams.
2. Use the formula:
* moles = mass (g) / molar mass (g/mol)
3. Plug in the values:
* moles = 0.0034 g / 195.084 g/mol
* moles ≈ 1.74 x 10^-5 mol
Therefore, there are approximately 1.74 x 10^-5 moles of platinum in 0.0034 grams.
