Calculate each of the following.
Part A
number of Ag atoms in 0.125 mole of Ag
Part B
number of C3H8O molecules in 0.925 mole of C3H8O
Part C
number of Cr atoms in 7.00 moles of Cr
Part A
number of Ag atoms in 0.125 mole of Ag
1 mol contain -------------- 6.023 x 10^23 atoms
0.125 mol Ag --------------- ?? atoms
number of Ag atoms = 0.125 x 6.023 x 10^23
= 7.529 x 10^22 atoms
Part B
number of C3H8O molecules in 0.925 mole of C3H8O
number of C3H8O molecules = 0.925 x 6.023 x 10^23
= 5.571 x 10^23 molecules
Part C
number of Cr atoms in 7.00 moles of Cr
number of Cr atoms = 7.00 x 6.023 x 10^23
= 4.216 x 10^24 atoms
