Question

200g of H2O and 100g of CO2 which has the greater number of moles and calculate​​

Answer 1

Answer:

I'm assuming you are asking about Calcium Carbonate. Be careful when writing chemical equations, the formula for Calcium Carbonate is CaCO3 not CaCo3.

So first you have to calculate the molar mass of CaCO3. We have one atom each of Calcium and Carbon and three atoms of Oxygen in one molecule of CaCO3. So the molecular mass will be

40u +12u +(16*3)u

=100u

Now the molar mass will be the molecular mass in grams. So the molar mass of CaCO3 is 100grams. This means 1 mole of CaCO3 is equal to 100g.

=> 1g of CaCO3 = 1/100 mole

=> 1*200 g = (1/100) * 200 moles

=> 200g of CaCO3 = 2 mole
