Answer to Question #250468 in Chemistry for ilyana

Question

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]

Answer 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 (N_a).

Hence,

(0.005 mol) × (6.02×10²³ molecules / 1 mol) = 3.01×10²¹ molecules of the flavoring substance

Answer: The number of molecules of the flavoring substance is 3.01×10²¹
