find a) calculate the moles and grams of hexamminecobalt(III) trichloride Table: Chemical Name Weight (g) No of Molar ratio moles/Molarity Pentaaminechlorocobalt(III) 6.018g dichloride Hexamminecobalt(III) chloride 0.024moles 2.510g 0.0094moles Calculations: pentaaminechlorobalt(III) dichloride Mass of clockglass = 26.002g Mass of (clockglass+product)%= 32.02g (Mass clockglass+product)-(Mass of clockgalss) = 6.018g

18.1 g of ammonium carbonate into moles of ammonium carbonate

what amount of Al2O3 is produced from the reaction of .30 mol. Al with 2.0 mol Fe2O3

Only question 14

How do you determine percent yield given 9.13 mL benzyl alcohol gives 8.58 mL benzaldehyde?

question number 2

Thanks for helping me find the percent yield

1. Use the molar masses of the elements in the product to calculate the number of moles of eachelement that reacted to form the compound  2. Calculate the ratio between the number of moles of each element in the product you made. Whatis the empirical formula of your compound? Remember to round up your empirical formula to thenearest whole number ratio.   Mass of crucible &  lid (g) Mass of crucible, lid & Mg ribbon (g) before heating  Mass of crucible, lid, & product after 1st heating (g) Mass after 2nd heating required (g)  Mass after 3rd heating required (g)  Mass after additional heating (s), if needed (g) 34.30 g  34.47 g  34.57 g  34.58 g  N/A  N/A

44 grams of carbon dioxide was formed after combustion of 12 grams of methane gas. Calculate theoretical yield, and percent yield of the reaction
