Given 5 moles of NaCl, which conversion factor would allow you to determine the number of molecules?

• 1 mol = 58 g

• 1 mol = 23 g

• 1 mol = 35 g

Who discovered the mole?

• Albert Einstein

• Lil' Nas

• Amedeo Avogadro

• John Dalton

• 1 mol = 74 g

What is Avogadro's Number?

• 602

• 305

If a dozen = 12, how much does a mole equal?

• 18 g

• 184 g

• (1x24) + (1x 16) + (2 x 1) = 42 g/mol

• (1x24) + (2x16) + (2x1) = 58 g/mol

• (2x24) + (2x16) + (2x1) = 82 g/mol

• (1x24) + (1x16) + (1x1) = 41 g/mol
