a) Molar mass of CaCO3 = 40 + 12 + 16x3 = 100 g/mol Mass of CaCO3 = (4.86 mol) x (100 g/mol) = 486 g b) No. of moles of CO3²⁻ ions = No. of moles of CaCO3 = 4.86 mol Molar mass of CO3²⁻ ions = 12 + 16x3 = ...
Finally, add together the total mass of each element to get the molar mass of 7CaCO3: 280.546 g/mol + 84.0749 g/mol + 335.9874 g/mol =700.6083 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in 7CaCO3, divide each total from step 3 by the to...
Emiliania huxleyi is a marine alga which produces coccoliths, elaborate calcified structures consisting of CaCO 3 and a water-soluble acidic polysaccharide. The polysaccharide was subjected to light scattering measurements to determine the weight-average molar mass ( M w) and osmometry to assess the ...
