The molar mass of O 2 is 32.0 g/mol. What mass, in grams, of O 2 must react to form 3.80 mol of Al 2 O 3 ?

everyone. So you were asked to determine the mass of burning gas Produced from the reaction of seven moles of hydrogen bromide with excess potassium sulfate. We're gonna need to convert from walls of hydrogen bromine to malls of romaine gas And then two g of drumming gas. Do I have 7.0 malls of hydrogen bromine? And we have two moles of hydrogen bromine and the reaction in one mold of propane gas in the reaction. And in one bowl of propane gas, we have the molar mass. And this is to I'm 79. And just give us 159 0.8 g. We're gonna get 559 0.3 grams of propane gas. Thanks for watching my video and I hope it was helpful.
