QUESTION:

The atomic mass of \(Cl\) is 35.45 amu, and the atomic mass of \(A1\) is 26.98 amu. What are the masses in grams of 3 mol of \(A1\) atoms and of 2 mol of \(Cl\) atoms.

ANSWER:

Step 1 of 2
Mass in gram of 3 mol of \(Al\) atoms:
Atomic mass of  \(Al\) = 26.98 g/mol
The mass of 3 mol of \(Al\) atom is = 3 mol 26.98 g/mole = 80.94 g 
Thus the mass of 3 mol of \(Al\) atom is found to be 80.94 g.
