Ga2(CO3)3 -> Ga2O3 + 3CO2
Gallium (III) Carbonate and Gallium Oxide are equimolar so 55 moles of gallium carbonate must be used.
The Molar Mass of Gallium (III) Carbonate is about 319 g/mol
319 g/mol (55 mols) = 17,545 g

What is the formula for gallium III carbonate and gallium III oxide?
gallium (III) carbonate - Ga2(CO3)3 gallium (III) oxide - Ga2O3
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.)
What mass of copper oxide will be obtained by heating 12.35gm of copper carbonate?
The easiest way to solve these problems is to use what is called a unit multiplier. First begin with the number of grams of copper that you have, then use the unit multiplier that expresses the number of grams per mole of copper (this is the number that corresponds to the atomic mass on the periodic table times grams, divided by moles). Then use the number of copper atoms that it takes to create copper oxide; this will depend on the oxidation state of the copper. Finally it reverse the process by adding up the atomic masses of copper oxide, and that will be the number of grams per mole of copper oxide, returning you from Moles back to Grams.
What Is Ga2c2o43?
Gallium Sulfate is expressed as Ga2(SO4)3.It is a combination of Gallium (GA), oxygen (O) and sulfur(S). It has the molecular mass of 427.6338 g/mol.
How many moles of aluminum oxide are present in a sample having a mass of 178.43g?
For this you need the atomic (molecular) mass of Al2O3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Al2O3= 102 grams408 grams Al / (102 grams) = 4.00 moles Al
What mass of calcium oxide is produced by heating 25 moles of calcium carbonate?
1400 grams
What is the formula for gallium III carbonate and gallium III oxide?
gallium (III) carbonate - Ga2(CO3)3 gallium (III) oxide - Ga2O3
