What is the molar mass of CaSO4? What mass of sodium chloride solute is needed to make 15 cm^3 of 4.500 M sodium chloride solution? What is the mass of KNO3? Molar mass of KClo3? What is the molar mass of Fe(NO3)2? What is the molar mass of Fe(NO3)2*9H20 What is sodium sul...
The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, KClO3*KCl: ElementNumber of Atoms K (Potassium) 2 Cl (Chlorine) 2 O (Oxygen) 3 2. Find Atomic Mass of Each Element Next, using the periodic table, ...
Finally, add together the total mass of each element to get the molar mass of 2KClO3 + 2KCl + 3O2: 156.3932 g/mol + 141.812 g/mol + 191.9928 g/mol = 490.198 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in 2KClO3 + 2KCl + 3O2, divide ...
