What mass of carbon monoxide is needed to produce 143.9g of iron according to Fe2O3 3CO --2 Fe 3CO2?
To find the mass of carbon monoxide needed, we need to use the stoichiometric ratio between iron and carbon monoxide. From the balanced equation, we can see that 3 moles of carbon monoxide produce 2 moles of iron. First, calculate the molar mass of iron (Fe), which is 55.85 g/mol. Next, use the molar ratio between iron and carbon monoxide (2:3) to find the moles of carbon monoxide required. Finally, convert the moles of carbon monoxide to grams using its molar mass (28.01 g/mol).
What is the molar mass of Co(NO2)3?
196.9497 g/mol
Is carbon monoxide heavier than air?
Molar mass of CO (carbon monoxide) is 12+16 = 28 ,the mean molar mass of air (20% O2, 80% N2) = 0.20*32 + 0.80*28 = 28.8 thus air is a bit heavier than CO
Where does most of the mass of glucose come from?
Carbon dioxide (CO^2)
Calculate The percent Water In CoC2H3O22 x 4H2O?
1. Find the molar mass (MM) of the hydrate (cobalt acetate tetrahydrate).MM Co(C2H3O2)2: 177.02g (anhydrate)+ MM 4H2O: 72.06g (water)MM Co(C2H3O2)2 * 4H2O = 249.08g (hydrate)2. Find the percent water of hydrate. Divide the mass of water by the mass of hydrate (anhydrate + water = hydrate).72.06g249.08g x 100%Percent water of hydrate is 28.93%.Finding Molar Mass# atoms Element A * Atomic Mass Element A = Mass A# atoms Element B * Atomic Mass Element B = Mass B... etc.Add up all of the mass values and you have the molar mass of the substance.
What is the molar mass of carbon dioxide?
Carbon monoxide, CO, has one atom of carbon and one atom of oxygen. The molar mass of carbon is 12.0107 g mol-1 and the molar mass of oxygen is 15.9994 g mol-1, so the molar mass of CO is 28.0101 g mol-1.
What is the number of molecule of G of CO?
The number of molecules of 140g of CO is 3.01x10^24 molecules of CO. CO is Carbon monoxide, with the mono meaning one. It's molar mass is 28.01 g/mol.

What is the percentage composition for CO?
The molecular mass of CO is 28. The carbon percentage by mass is ~43%. Hence the oxygen percentage by mass is ~57%.
What mass of carbon monoxide must react with oxygen to produce 0.69g of carbon dioxide?
0.44g CO
What is the mass in grams of 0.0489 mol cobalt?
The gram atomic/molar mass of cobalt is 63.546. Multiplying this number by 0.0489 yields the answer of 3.11 grams, to the justified number of significant digits.
