What is the molecular mass of vitamin K C31H46O2?

Answer 1

Atomic Mass for carbon,hydrogen and oxygen are 12,1 and 16 respectively.since the molecular formula of vitamin K is C31H46O2, then the respective atomic mass for each element are substituted in the molecular formula. That is,the total number of carbon present is 12 multiplied by 31 which gives 372,the total number of hydrogen present is 1 multiplied by 46 which gives 46,and finally the total number of oxygen present is 16 multiplied by 2 which gives 32.The total addition of all these gives the molecular mass 450g.

answer 450.7

Answer 2

To calculate the molecular mass of a compound, you need to add the atomic masses of all the atoms in the formula. The molecular mass of vitamin K (C31H46O2) can be calculated by adding the atomic masses of 31 carbon atoms, 46 hydrogen atoms, and 2 oxygen atoms. The atomic masses for one mole of each element are approximately 12 g/mol for carbon, 1 g/mol for hydrogen, and 16 g/mol for oxygen.
