QUESTION:
Calculate the number of atoms in each sample.
a. 5.18 g P b. 2.26 g Hg
c. 1.87 g Bi d. 0.082 g Sr
ANSWER:Solution 87:Here, we are going to calculate the number of atoms in each sample.Step 1:a. 5.18 g PWe know that,The molar mass of P = 30.97 g/mol.Thus, the mol of P = 5.18 g P × 1.0 mol P= 0.167 mol P 30.97 g PSimilarly,1.0 mol P contains 6.022 × 10 atoms P 6.022×10 atoms PTherefore, the number of P atoms = 0.167 mol P × 1.0 mol P 23 = 1.0 × 10 Patoms
