Question

1. halloween is just around the corner! the chemical formula for sugar, the main ingredient in candy, is ( c_{12}h_{22}o_{11} ), and its molar mass is 242 g.

if susie is hoping to get 1 mole of pieces of candy when she goes trick - or - treating, how many pieces of candy does susie want?
342
( 1.76\times10^{21} )
( 2.06\times10^{26} )
( 6.02\times10^{23} )

Explanation:

Step1: Recall Avogadro's number

Avogadro's number \(N_A = 6.02\times10^{23}\) particles per mole.

Step2: Calculate the number of pieces

Since Susie wants 1 mole of pieces of candy, and by definition, 1 mole of any substance contains \(6.02\times 10^{23}\) entities (in this case, pieces of candy).

Answer:

\(6.02\times 10^{23}\)
