So, lets assume that you have 150 grams of CaCO3 and you are being asked how many moles of CaCO3 you have. The moles of CaCO3 which are there in antacid tablet that contain 0.515g CaCO3 is calculated as follows moles = mass/molar mass the molar mass of CaCO3 = (40 x1) + (12 x 1) + (16 x 3) = 100 g/mol moles is therefore = 0.515g/100 g/mol = 5.15 x10^-3 moles 100grams per mole. the number of carbon atoms in 1g of caco3 is About; FAQ; Contacts; Location The moles of CaCO3 which are there in antacid tablet that contain 0.515g CaCO3 is calculated as follows moles = mass/molar mass the molar mass of CaCO3 = (40 x1) + (12 x 1) + (16 x 3) = 100 g/mol moles is therefore = 0.515g/100 g/mol = 5.15 x10^-3 moles How many moles of oxygen are present? One tablet reacted with excess HCl acid to produce 0.24 dm^3 of CO2 at r.t.p." The first thing you need to figure out is the molar mass of CaCO3 and you do this with the help of a periodic table. "Each tablet contains the same number of moles of CaCO3 and MgCO3. Genesis is right, you seem to be missing a key piece of information, such as the mass of CaCO3 that you are dealing with.

And thus.....for #"calcium carbonate....."# #"Number of moles"=(250*g)/(100.09*g*mol^-1)=?? Click hereto get an answer to your question ️ How many moles of calcium carbonate (CaCO3) are present in 20 g of the substance? ( Ca = 40, C = 12, O = 16 ) Menu. Hi there. The question is about how many moles of CaCO3 AND MgCO3 are in a tablet. Introduction; DISPLACEMENT; LEROS; Essay; Photo; The PLAN and the OBJECTS; how many total atoms are in limestone, caco3? CaCO3 + 2HCl --> CaCl2 + CO2 + H2O MgCO3 + 2HCl --> MgCl2 + CO2 + H2O (i) Calculate how many moles of CaCO3 there are in one tablet. Molar mass of CaCO3 is 100.0869 g/mol Compound name is calcium carbonate Convert between CaCO3 weight and moles CaCO3 = Ca2+ + CO3 2-, ratio of CaCO3 to Ca2+ moles is 1: 1 so number of moles of CaCO3 is exactly the same as number of moles of Ca2+ Molecular weight for calcium carbonate, CaCO3 = 40 + 12 + (16x3) = 100g/mol or 100mg/mmol; Dose as before for 30 days = 90g or 90000mg Molar mass of CaCo3(chalk) is 216.8776 g/mol Convert between CaCo3(chalk) weight and moles Homework Statement In 0.50 moles of CaCO3 how many moles of carbon are present? *mol#.
