How many objects are in one mole?</p><p>2. What is the mass of 1 mole of gold (Au)?</p><p>3. What is the mass of 1 mole of glucose (C6H12O6)?</p><p>4. If you had 24.65 grams of aluminum chloride, how many moles would that be?</p><p>5. Which would have a greater mass: 2 moles of hydrogen or 1 mole of lithium?</p><p>Hypothesis: I think that the mass of one mole of split peas will be ______</p><p>I think that the volume of one mole of split peas will be______</p><p>Materials: Plastic cup 8</p><p>Balance</p><p>Split Peas</p><p>100mL graduated cylinder</p><p>Procedures: 1. Determine the mass of 25 split peas.</p><p>2. Fill a 100mL graduated cylinder with split peas.</p><p>3. Determine the mass of 100mL of split peas.</p><p>4. Use the data gathered to complete the data table.</p><p>Data Table:</p><p>Mass</p><p>Mass of 25 split peas: ______grams</p><p>Mass of 1 split pea: (Mass of 25 split peas / 25) ______grams</p><p>______</p><p>Volume</p><p>Mass of 100mL of split peas: ______grams</p><p>Number of split peas in 100mL:</p><p>(Mass of 100mL of split peas / Mass of 1 split pea)</p><p>______split peas</p><p>Volume of 1 split pea:</p><p>(100mL / number of split peas in 100mL)</p><p>______mL</p><p>______</p><p>Molar Mass of Volume</p><p>Mass of one mole of split peas:</p><p>(Mass of 1 split pea X 6.02 x 1023) ______grams 8</p><p>Volume of one mole of split peas:</p><p>(Volume of 1 split pea X 6.02 x 1023) ______mL</p><p>Post Lab Questions (in complete sentences):</p><p>1. How did your hypothesis compare to the calculate molar masses and volumes?</p><p>2. Why was the mass of 25 split peas determined rather thatn the mass of just one split pea?</p><p>3. Using your data, what would be the mass of 100 split peas? What would be the volume of 100 split peas?</p><p>4. Why do we use Avogadro’s number when discussing atoms?</p>
