Answer:
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
