What is the empirical formula?1. Find the Number of Moles of Each Element The molar mass of hydrogen is 1 g (rounding to one decimal place), so the number of moles present in the compound is 0.675/1 = 0.675. The molar mass of oxygen is 16 g, and the molar mass of calcium is ...
Now that you know what a mole is and what molar mass refers to, where do you find this number? You can find it for each element on the periodic table. If you look underneath the symbol for each element, you will find a number. The molar mass of elements is given by that number,mo...
The mass of one mole of an element or a compound is equal to the mass number of the molecule expressed in the units of a gram. We can find the moola mass of a compound or an element from the molecular formula. To find the molar mass, we have to add the molar mass of each atom ...
To find the percent yield the actual yield is divided by the theoretical yield the resulting answer is multiplied by 100. What is the formula for the theoretical yield? We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass of the...
Two oxides of a metal contain 27.6% and 30% of oxygen respectively. If the formula of the first oxide is MO, find that of the second? Now my problem is how to find the atoms of O from the masses of 27.6% and 30.0 %? How to get atoms of something having % of mass? I am conf...
