What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
What is molecular number for kapok seed oil?
The relative molecular weight of kapok seed oil is 875.081.
What are the fractions of each type of atom in methane?
The molecular formula of methane is CH4. Therefore, the number of atoms per molecule is 5, the fraction of the atoms that are carbon is 1/5 and the fraction of the atoms that are hydrogen is 4/5.
If empirical formula is C2H5 what is molecular formula?
The molecular formula would have to be C4H10 as the number of hydrogen atoms cannot exceed 2+2X where X is the number of carbon atoms.
Mass number used to calculate the number of?
the mass number of an atom is used to calculate the number of neutrons and protons in the nucleus of an atom
A fraction between 0.625 and 0.7?
If you calculate the average of the two numbers, you'll get a number that is between the two. That will be a decimal; you can then convert it into a fraction.
Number-average molecular weight of a polypropylene is 1000000 gmol Compute the number-average degree of polymerization?
i got 23765.4
If you have the average how to calculate the total?
Multiply the average by the number of terms.
The line that divides a fraction?
The line that separates the top number (numerator) from the bottom number (denominator) of a fraction can be called a dividing line - since this is what is happening in the sum itself to calculate the fraction.
How to calculate empirial formula from molecular formula?
Calculate the empirical formula weight. Find the ratio of the molecular weight to the empirical formula weight. (n= molecular weight/ empirical formular weight). Multiply each subscript of the empirical formula by n.
How to calculate average change IN INVENTORY?
You calculate average change in inventory by dividing the turnover by how many times it has turned over. The number you get is the average.
How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
Firstly, calculate the molecular volume by dividing the product of molecular density and the molecular weight by the Avogadro number. Then take a third root of the volume, the found value is the atomic radius. Then multiply it by 2 to find the diameter.
How are molecular weights found from titration?
The results of a titration will tell you the number of moles present in the analyte. If you then also know the mass of this analyte, you can calculate the molecular weight as mass/moles.
How do you calculate the average of a list of numbers?
If you want to calculate the average of a list of numbers, add the numbers together and divide it by the number of numbers.
Are decimals just as important as whole numbers?
Of course! Without decimals, you couldn't calculate percentages or fractions. Decimals allow you to break a number up. A decimal is basically a fraction, and when you calculate fraction adding, subtraction, multiplication, and division, sometimes it is easier to calculate a fraction by first changing it to a decimal instead.
How do you calculate average value?
(sum of data)/number of data
