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 ...
2ndStep:Calculate the Empirical Formula mass (EFM) by adding up the molar atomic masses of all atoms constituting the formula. 3rdStep:Determination of the Molar Mass of the given compound. 4thStep:Determination of the value ‘n’. It is done by dividing the molar mass of the compound by ...
The person solving this problem needs to calculate the total probability of the animal living 14.6 years or longer. The empirical rule shows that 68% of the distribution lies within one standard deviation, in this case, from 11.6 to 14.6 years. Thus, the remaining 32% of the distribution lie...
