How many miles are 248 grams of phosphorus (P4)? How many atoms are there in the same amount of phosphorus?

2 moles, 1.2044 * 10²⁴ particles/atoms

Explanation:

P4 = 4(30.974) = 123.896

To find the moles, we need to divide grams/the atomic mass..

248/123.896 = 2.001678827 moles or just 2 moles

To convert from moles to atoms, we need to multiply by avogadro's number (6.022*10²³)

After plugging this into out calculator, we have 1.2044E24, which basically means 1.2044 * 10²⁴ particles/atoms
