Question

How many moles are in 2.3 grams of Phosphorus?

Answer 1

Answer:

There are approximately 0.074 moles in 2.3 grams of phosphorus.

Explanation:

To determine the number of moles in 2.3 grams of phosphorus, we need to know the molar mass of phosphorus. The molar mass of phosphorus is 30.97 g/mol.

To calculate the number of moles, we can use the formula:

moles = mass (in grams) / molar mass

Substituting the values, we get:

moles = 2.3 g / 30.97 g/mol

moles = 0.074 moles (rounded to three significant figures)

Therefore, there are approximately 0.074 moles in 2.3 grams of phosphorus.

This calculation is useful in chemistry, where it is common to measure the amount of a substance in moles rather than in grams. Moles are a unit of measurement that allows us to compare different substances on a more equal footing, and to perform calculations that involve chemical reactions and other properties of matter.
