How do you calculate the molecular formula of a substance which contain 80 percent C and 20 percent H?
You can only calculate the empirical formula because you do not have a mass of this compound given. To do the empirical formula assume 100 grams and change percent to grams. Get moles. 80 grams Carbon (1 mole C/12.01 grams) = 6.66 moles C 20 grams hydrogen (1 mole H/1.008 grams) = 19.84 moles H the smallest becomes 1 in the empirical formula and the other number is divided by it, Thus; H/C 19.84 moles H/6.66 moles C = 2.9, which we call 3 so, CH3 --------------- is the empirical formula To get the molecular formula tour question needed to read; How to calculate molecular formula from such ans such mass of compound with these percentages of elements, Which, of course, your question did not provide. Then you would have divided that given mass by the mass total of the elements of the empirical formula, got a whole number by which you would have multiplied the numbers of your empirical formula to get molecular formula.

What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
How do you calculate daily compound interest?
If the annual interest rate is r%, then the equivalent daily compound rate is100*{(1 + r/100)^(1/365) - 1} %where the exponent of (1/365) represents the 365th root.You could adjust for leap years either by using 365.25 or using a different rate for leap years.

How do you calculate the empirical formula using percentages?
To calculate the empirical formula using percentages, first convert the percentages to grams. Then divide the grams by the element's molar mass to find the moles. Finally, divide the moles by the smallest number of moles to get the ratio of elements in the compound, which represents the empirical formula.
The formula of a compound with the smallest ratios is called?
The formula of a compound with the smallest ratios is called the empirical formula. It represents the simplest whole-number ratio of atoms in a compound.
What is the empirical formulae for phenol?
