Materials similar-sized pieces of lead, copper, zinc and sulfur salt (NaCl) sugar (sucrose) water balance 10-mL graduated cylinder cylinders containing one mole of the following water glycerine iron filings copper sand sugar (C12H22O11) Procedure PART I 1. Find the mass of each of the element samples (lead, copper, zinc and sulfur). 2. Measure 5.0 g of each of the compound samples (salt, sugar, water). 3. Using the molar mass of each of the substances, determine how many moles are present in each sample.. 4. Using Avogardros number, determine how many particles are in each sample. Record this information in the data table below.. Data LEADCOPPERZINC SULFURSALTSUGARWATER MASS (g)  MOLES  PARTICLES  Calculations 1. Calculate the MOLES of each substance. 2. Calculate the NUMBER OF PARTICLES of each substance. Procedure PART II 1. Examine the 1-mole samples provided to you in the graduated cylinders. Compare the 1 mole samples with each other. 2. Read the volume that 1 mole of each substance occupies from the graduated cylinder and complete the following table..

List the elements you investigated in order from samllest to greatest mass. 2. List the elements you investigated in order from smallest to greatest number of moles. 3. List the elements you investigated in order from smallest to greatest number of particles. 4. Is the number of particles in the sample directly proportional to the mass or the number of moles? 5. Compare the number of particles in each of the 5.0 g samples of the compounds you investigated. Explain why a 5.0 g samples of water does not have the same number of particles as 5.0 g of sugar. 6. How many grams of sugar would you need to have the same number of particles as 5.0 g of salt?
