How do you convert from moles to gram?
It depends on the RMM (relative molecular mass) of the molecule your dealing with. For example if you had 2 Moles of ethene (C2H4) then you would simply multiply the number of moles by the RMM, which for ethene is approximately 28 [2C=24 +4H=28] So just multiply the RMM (28) by the number of moles(2) which gives 56g so 2 Moles of C2H4 weighs 56g.
How many grams of calcium carbonate are required to prepare 50.0 g of calcium oxide?
This is a mass stoichiometry problem. Start with the balanced equation: CaCO3 --> CaO + CO2. Do a conversion from 50g CaO to moles: 56g/1mol=50g/x, x=.9 moles. The equation is balanced as written, with all coefficients understood to be 1. So: .9 moles CaO means .9 moles CaCO3. Do another conversion from moles to grams: 100g/1mol=x/.9 moles. Solve for x to get 90 grams. (56g=molar mass of calcium oxide; 100g=molar mass of calcium carbonate.)
Which will have a greater volume 1 kilogram of copper or 1 kilogram of iron?
M(Cu)=64g/mol, M(Fe)=56g/mol, so Iron has greater volume.
What is the percent yield for iron if the reaction of 65.0 g of iron oxide produces 33.0 g of iron?
Well, I ran the numbers for what you have in the question, and it didn't make sense, so I'm assuming you really mean 65g of iron yields 33g iron oxide. I'm also assuming you mean iron(III) oxide, which is iron's most common valence state when it reacts with oxygen, which means the product's formula would be Fe2O3.With those things in mind, here's your balanced equation:4Fe + 3O2 --> 2Fe2O3.Step1: given 65g Fe, how many moles is that? Direct proportion between 65g and the unknown # of moles and iron's atomic mass of 56g/mol gives us 1.16 moles of iron.Step 2: molar ratio of iron to iron(III) oxide is 4-2, which simplifies to 2-1, so you will have 0.58 moles of product.Step 3: given 0.58 moles of product, set up another direct proportion with the unknown mass over given moles equal to iron(III) oxide's molar mass of 160g/mol to get a mass of 92.8g theoretical yield of product.Step 4: your actual yield was 33g, so divide that by the stoichiometric yield of 92.8g, which is 0.355, which means about a 36% actual yield, which is the answer.
What is the significant figures for 56g?
