To find out how many moles are in 2.3 grams of phosphorus, we first need to know the molar mass of phosphorus. The molar mass of phosphorus (P) is approximately 30.97 grams per mole.
Next, we use the formula to convert grams to moles: moles = mass (g) / molar mass (g/mol).
Plugging in the values we have:
moles = 2.3 g / 30.97 g/mol
Calculating this gives us:
moles ≈ 0.0742 moles
So, there are approximately 0.0742 moles of phosphorus in 2.3 grams.
