0.58g of flavoring substance is used to improve the taste of the pineapple cake. What is the number of molecules of the flavoring substance? [RMM flavoring substance = 116 gmol-1]
Solution:
RMM flavoring substance = 116 g mol-1
Hence,
(0.58 g) × (1 mol / 116 g) = 0.005 mol of flavoring substance
One mole of any substance contains 6.02×1023 formula units (Na).
Hence,
(0.005 mol) × (6.02×1023 molecules / 1 mol) = 3.01×1021 molecules of the flavoring substance
Answer: 3.01×1021 molecules of the flavoring substance
