Calculate the molesnof the substance using the following formula: n =m/M The quantity of substancenin moles is equal to the massmin grams divided by the molar massMin g/mol. For example,let’s calculate the quantity in moles equal to 120 grams of aluminum oxide, Al2O3. Note that the...
Q.When $\mathrm{CO}_{2}$ (g) is passed over red hot coke it partially gets reduced to CO(g). Upon passing 0.5 litre of $\mathrm{CO}_{2}$ (g) over red hot coke, the total volume of the gases increased to 700 mL. The composition of the gaseous mixture at STP is :-(1) $...
Mole fraction is a way to state the concentration of a mixture. It is expressed as the ratio of moles of one components to the total moles of the mixture.
If all the moles at this point are whole numbers (or very close), the empirical formula can be written with the moles as the subscript of each element. In some cases, one or more of the moles calculated in step 3 will not be whole numbers. Multiply each of the moles by the smallest...
