Ascorbic acid, or vitamin c is an essential vitamin. it cannot be stored by the body and must be present in the diet. what is the molar mass of ascorbic acid? vitamin c tablets are taken as a dietary supplement. if a typical tablet contains 546.0 mg vitamin c, what amount (moles) and what number of molecules of vitamin c does it contain?

Molar mass of ascorbic acid=176.13 g/mol

Number of moles in a  ascorbic acids tablet contain 546 mg =

Number of molecules in a tablet of ascorbic acid of mass 546 mg= molecules

Explanation:

We are given that ascorbic acid or vitamin C is an essential vitamin

We are given that given mass of ascorbic acid in a tablet =546.0 mg=

We have to find the number of moles and molecules of vitamin in C

We know that the chemical formula of ascorbic acid

Molar mass of vitamin C =6(12.011)+8(1.0079)+6(16)=176.13 g/mol

Number of moles=

Number of moles of vitamin C=

Number of moles of vitamin C=0.0031 moles=

Number of molecules of vitamin C=

Where Avogadro's number =

Number of molecules of vitamin C=

=molecules
