Molar mass of CaCO3 is 100.0869 g/mol Compound name is calcium carbonate Convert between CaCO3 weight and moles *mol#. 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)=?? Molar mass of CaCo3(chalk) is 216.8776 g/mol Convert between CaCo3(chalk) weight and moles 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. Menu. Click hereto get an answer to your question ️ How many moles of calcium carbonate (CaCO3) are present in 20 g of the substance? "Each tablet contains the same number of moles of CaCO3 and MgCO3. ( Ca = 40, C = 12, O = 16 ) Homework Statement In 0.50 moles of CaCO3 how many moles of carbon are present? Introduction; DISPLACEMENT; LEROS; Essay; Photo; The PLAN and the OBJECTS; how many total atoms are in limestone, caco3? the number of carbon atoms in 1g of caco3 is About; FAQ; Contacts; Location How many moles of oxygen are present? 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. CaCO3 + 2HCl --> CaCl2 + CO2 + H2O MgCO3 + 2HCl --> MgCl2 + CO2 + H2O (i) Calculate how many moles of CaCO3 there are in one tablet. One tablet reacted with excess HCl acid to produce 0.24 dm^3 of CO2 at r.t.p." Hi there. 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 The question is about how many moles of CaCO3 AND MgCO3 are in a tablet. 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 Tu Tetera
