# Question: What is the mole of phosphorus?

Contents

If we check on the periodic table, the molar mass of phosphorus is about 30.97 gmol .

## How do you calculate moles of phosphorus?

You can go about it more directly as follows. You have (15.95/283.889)=0.0562 moles of P4O10. From the molecular formula you see that for every mole of P4O10 you have 4 moles of phosphorous. Therefor you have 4×0.0562=0.2247 moles of phosphorous.

## What is the molar mass for phosphorus?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

## How many moles of phosphorus are in phosphate?

If the formula unit represents 1 mole of copper(II) phosphate , then there are 2 moles of phosphorus per 1 mole copper(II) phosphate formula units. One mole of atoms = 6.022×1023 atoms .

## How much atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many moles of phosphorus are in P2O5?

We use this factor because there are 2 moles of P in every 1 mole of P2O5.

## What is the total mass of phosphorus?

The molar mass of Phosphorous is 123.88 g/mol.

## How do you find the mass number of phosphorus?

The mass number of phosphorus is 31.

This means that there are a total of 31 protons and neutrons in the nucleus of the most common isotope of…

## What is a 1 mole?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## What is a mole in chemistry?

A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs. Chemists have to measure using moles for very small things like atoms, molecules, or other particles.

## How do you find the mole fraction?

How to calculate the mole fraction of a solution? Mole fraction (Xsolute) = moles of solute / (moles of solute + moles of solvent) .

## How many atoms are there in 5 mole of phosphorus?

So you have to understand what is the mole . Think that 1mole is a packet which can hold 6.02×10^23 molecules or atoms(depend on question , what you are exactly asked ) . Thus if 1mole contains 6.02×10^23 H2O molecules then 5moles will hold 5×6.02×10^23=3.01×10^24 H2O molecules. = 0.8071 moles.
