Question

What is the mass of 1 mol of atoms of P?

Answer 1

The mass of `1` mole of phosphorus atoms is approximately `30` `g`.

Explanation:

The mass of `1` mole of phosphorus atoms can be expressed as grams per mol (`g/(mol)`). This is also known as molar mass. If we check on the periodic table, the molar mass of phosphorus is about `30.97` `g/(mol)`.

To find the mass of `1` mole of phosphorus atoms, we can use the formula:

`m=nM`

where:
m = hass (grams)
n = number of moles
M = molar mass

`m=nM`
`m=(` `1` `mol)` `(30.97` `g/(mol)`)
`m=(` `1` `color(red)cancelcolor(black)(mol))` `(30.97` `g/(color(red)cancelcolor(black)(mol))`)
`m=(1)(30.97` `g`)
`m=30.97` `g`
`m=30` `g`

Note:
The final answer should always have the correct number of significant figures.

`:.`, the mass of `1` mole of phosphorus atoms is approximately `30` `g`.
