How many atoms are there in 5.24 grams of p?

To find the number of atoms in 5.24 grams of phosphorus (P), we first need its molar mass, which is approximately 30.97 g/mol. Using Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol), we can calculate the number of moles in 5.24 grams: (5.24 , \text{g} \div 30.97 , \text{g/mol} \approx 0.169 , \text{mol}). Multiplying the number of moles by Avogadro's number gives us approximately (1.02 \times 10^{23}) atoms of phosphorus.
