How do you calculate the molar mass of vitamin A?

Answer 1

Well, first you need the molecular formula of #"vitamin A"#.

I don't know it, but this site relates that vitamin A is a family of organic compounds that includes #"retinol"#, i.e. #C_20H_30O#, i.e. 6 degrees of unsaturation.

And #C_20H_30O# gives a molecular mass of...........

#(20xx12.011+30xx1.00794+16.00)*g*mol^-1=286.46*g*mol^-1.#

To calculate the molar mass of vitamin A, you would determine the atomic masses of all the elements present in its chemical formula and then sum them up according to the number of atoms of each element in the molecule.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
