The empirical formula is the molecular formula with the most reduced subscripts you can get. #5# is (of course) an odd number, and #2# is obviously an even number, but clearly you can't halve #5#. Therefore, #"N"_2"O"_5# is already an empirical formula.
What is the empirical formula of n2o5? N 2 O 5 already is an empirical formula, because there is no single integer by which both of its subscript numbers can be divided to produce an integer ...
Do the same thing for the second one, but the 3rd and 4th are different. N205 is already in its empirical formula. So the empirical formula for the third one is the same as what's given to you: N2O5 EDIT: Chris J is incorrect on the 4th one. The molecule is already in it's empirical formula. It's Potassium Dichromate.
The empirical formula is the molecular formula with the most reduced subscripts you can get. ##5## is (of course) an odd number and ##2## is obviously an even number but clearly you can’t halve ##5##. Therefore ##N_2O_5## is already an empirical formula. PLACE THIS ORDER OR A SIMILAR ORDER WITH LITE ESSAYS TODAY AND GET AN AMAZING DISCOUNT
Which molecular formula is also an empirical formula? (1) C6H6 (2) H2O2 (3) N2H4 (4) N2O5 . Answer and Explanation: An empirical formula is a formula where the subscripts of the elements are in their lowest whole number ratio.
The Empirical Formula and The Molecular Formula . The empirical formula is the simplest formula that exists in simplest whole numbered ratios. That is, it gives the number of moles of each element present in the lowest possible numbers. If you know the number of moles of each element, then you can write the empirical formula.
The empirical formual for N2O4 is NO2. If you are given the empirical formula and are asked for the actual formula, then the molecular mass of the compound will be given too.
Both the molecular formula and the empirical formula contain the correct relative number of atoms of each element present in a pure chemical substance. For molecular compounds the molecular formula will be the empirical formula multiplied by some integer value.
