Mole quiz

Mole Quiz- Test your comprehension on balancing equations, the mole, molar mass, and moles to grams, grams to mole and mole A to mole B conversions. Use your note resources. Use scratch paper and calculators if needed. Above all, write out all steps and units.

1

What is the value of Avogadro's number?

1

A molecule of Al2(SO4)3 contains:

Round atomic masses to the tenth when calculating molar mass.

1

The atomic mass of N is 14.0 g/mol, and the atomic mass of H is 1.0 g/mol. What is the molecular mass of NH3?

In questions with show your work, correct answers without work will lose a point. Incorrect answers, but correct work will be worth 1 pt.
