S(Sulphur/Sulfur)2 × 32.065 = 64.13 O(Oxygen)8 × 15.9994 = 127.9952 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of KAl(SO4)2: 39.0983 g/mol + 26.9815386 g/mol + 64.13 g/mol + 127.9952 g/mol =258.2050386 g/mol ...
Finally, add together the total mass of each element to get the molar mass of NaAl(SO4)2.12H2O: 22.98976928 g/mol + 26.9815386 g/mol + 67.9778 g/mol + 151.674312 g/mol + 2.01588 g/mol =271.63929988 g/mol 5. Find Mole Fraction
Write the empirical formula for the hydrated alum. (Hint: if the ratio of moles of H2O to moles of anhydrous KAl(SO4)2 was 4, then the empirical formula would be: KAl(S04)2 4H20). Show your work. What is the empirical formula of a ...
To find the values of x, you can heat a sample of the compound to drive off all of the water and leave only KAl(SO4)2. Assume you heat 4.74 g of the hydrated compound and that the sample loses 2.16 g of water. What is the value of x? 3. If “Epsom salt,” MgSO4 xH2O, ...
