Mole Concept

What is Avogadro's Number?

• 602

• 305

The mass of 1 mole is known as

• A mole

• Molar mass

• Percent Composition

• Grams

• 1 mol = 84 g

• 1 mol = 18 g

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

• 18 g

• 184 g

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

• (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

• 1 mol = 201 g

• 1 mol = 461 g

When do you need to calculate molar mass?

• Every time

• Given the chemical formula

• Given Moles and Molecules

• Given Moles and Grams

What is the molar mass of NaCl?

• (1x23) + (1x35) = 58 g/mol

• (1x23) x (1x35) = 805 g/mol

• (2x23) + (2x35) =116 g/mol
