Answer:
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
