Answer:
The answer to your question is 7.77 x 10²² molecules of Glucose
Explanation:
Data
Number of molecules = ?
Mass = 23.3 g
Molecular mass of Glucose = 180 g
Avogadro's number = 6.023 x 10²³
Process
1.- Calculate the moles of Glucose in 23.3
180 g ------------------ 1 mol
23.3 g ---------------- x
x = (23.3 x 1) / 180
x = 0.129 moles
2.- Use Avogadro's number to calculate the number of molecules
1 mol of Glucose ------------- 6.023 x 10²³ molecules
0.129 moles -------------- x
x = (0.129 x 6.023 x 10²³) / 1
x = 7.77 x 10²² molecules
