Explanation:
You said at least 6 methods meaning I can give more than 6.
Hope it helps.
I'd say conduction maybe I'm honestly not sure bc it has nothing to do with radiation so its between conduction and convection cause id guess they wouldn't want the heat to escape so it wouldn't be convection ???
There are approximately 6.02 × 10²³ atoms of phosphorus in one mole of 30.974 grams of phosphorus (option A).
<h3>How to calculate number of atoms?</h3>
The number of atoms of a substance can be calculated by multiplying the number of moles of the substance by Avogadro's number. That is;
no of atoms = no of moles × 6.02 × 10²³
According to this question, there are 30.974 grams of phosphorus in one mole of phosphorus. The number of atoms can be calculated as follows:
no of moles of P = 30.974g ÷ 31g/mol = 0.99mol
number of atoms = 0.99 mol × 6.02 × 10²³
number of atoms = 6.02 × 10²³ atoms
Therefore, there are approximately 6.02 × 10²³ atoms of phosphorus in one mole of 30.974 grams of phosphorus.
