Chapter 6.1, Problem 5RQ
Interpretation Introduction

Interpretation: This is to be determined whether 3.89 g of nickel or 6.61 g of silver contains more atoms..

Concept Introduction: A mole of a substance is defined as the mass in grams of the substance that contains 6.02×1023 units (atoms, molecules or ions of the substance). This mass is equal to the molar mass of the compound expressed in g.mol-1.

Expert Solution & Answer

Answer to Problem 5RQ

The given weight of nickel will contain more atoms.

Explanation of Solution

The atomic masses are

Ni: 58.693 g.mol1

Ag: 107.868 g.mol1

  Moles of Ni =(3.89 g)(58.693 g.mol1)=0.06628 mol

  Moles of Ag =(6.91 g)(107.868 g.mol1)=0.06406 mol

It is known that 1 mole of any substance contains 6.02×1023 units (atoms, molecules or ions) of the substance. Since there is more of the nickel sample than the silver sample (in terms of the number of moles), hence, the given weight of nickel will contain more atoms.

Conclusion

The given weight of nickel will contain more atoms.
