How many g are in 3.07 moles of CH4?(16.05g/mol,49.3g) 5. Find the molar mass of Na2SO3. How many moles are in 467.2gofNa2SO3 ? (126.05g/mol, 3.706molj) 6. Find the molar mass of sugar, CH12O6. How many moles are in 329g of sugar? (180.18 g/mol, 1.83mol) 7. Find the molar mass of sulfuric acid, H2SO4. How many g are in 0.033 moles of H2SO4 ? (98.09 g/mol,3.2g ) 8. Find the molar mass of CO2. How many moles are in 2.66g of CO2?(44.01g/mol,6.04mol) 9. How many molecules are in 5.06g of Cl2 ? Molar Mass Cl2 (70.9 g/mol, 4.301022 molecules) 10. How many grams are in 6.421010 molecules of Al(OH) ?? Molar Mass Al(OHh) (78.01 g/mol,8.321012g ) Percent composition, empirical and molecular formula problems: 1. What is the percent copper in CuNO3 ? 2. What is the percent oxygen in Zn(ClO2)2 ? 3. A sample of copper wire with a mass of 1.659g is heated with excess powdered sulfur until the copper has combined with the sulfur, and all the extra sulfur has been burned off. The final product (a sulfide of copper) has a mass of 2.491g. Calculate the empirical formula of the product. 4. A 0.750g sample of tin metal reacts with 0.201g of oxygen gas to form tin oxide. Calculate the empirical formula of the tin oxide. 5. A 1.164g sample of iron filings reacts with chlorine gas to give 3.384g of iron chloride. Calculate the empirical formula of the product. 6.
