Themolecular massor molecular weight is the total mass of a compound. It is equal to the sum of the individual atomic masses of each atom in the molecule. It's easy to find themolecular massof a compound with these steps: Determine themolecular formulaof the molecule. Use the periodic tabl...
Formula of a Compound: Empirical Formula Example An empirical formula will give the simplest whole-number ratio of atoms in a compound when the information given is the mass of each element and not the name of the compound. Step 1:Note the number of grams given in the problem: 40.50 g Ca...
It's either the easiest way to double or even triple your savings, or a sure-fire ticket to bankruptcy. Let's explain. First of all, compound interest is different from simple interest. Simple interest is a fixed rate over time, based on the initial amount you've invested. If you've ...
To calculate empirical formula of a compound, find the mass of each element present in the compound and convert it to moles, calculate the individual mole ratios and then write out the empirical formula. There are numerous ways in which information regarding the molecular structure and composition ...
