Question

The molar mass of p4 is 124 g/mol. use this to calculate the number of moles of p4

Answer 1

The number of moles of P4 is 1 mol.

Step-by-step explanation:

The molar mass of P4 is 124 g/mol. To calculate the number of moles of P4, we use the formula:

moles = mass / molar mass

Substituting the given values into the formula, we get:

moles = 124 g / 124 g/mol = 1 mol

Therefore, the number of moles of P4 is 1 mol.

Answer 2

To calculate the number of moles of P4, divide the given mass by the molar mass (124 g/mol). The specific mass of the P4 sample is needed to perform the calculation. Without it, we cannot compute the number of moles.

Step-by-step explanation:

To calculate the number of moles of P4, you need to divide the given mass of the substance (in grams) by its molar mass (in g/mol). However, the mass of the P4 sample has not been provided in the question, so it's not possible to perform the actual calculation without this information. If you have a specific mass for a sample of P4, you can use the molar mass of 124 g/mol to find the number of moles by using this formula:

Number of moles = Mass of the substance (g) / Molar mass (g/mol)

For example, if the mass of P4 is 2 grams, the number of moles would be:

Number of moles = 2 g / 124 g/mol = 0.0161 mol
