How many molecules of glucose are in 1,456 grams of glucose? 1. 8.77x10^26
2. 1.08x10^26
3. 4.87x10^24
4. 1.34x10^-23

4.87×10²⁴ molecules

Explanation:

Given data:

Mass of glucose = 1456 g

Number of molecules = ?

Solution:

Number of moles of glucose:

Number of moles = mass/molar mass

Number of moles = 1456 g/ 180.156 g/mol

Number of moles = 8.1 mol

1 mole of glucose contain 6.022×10²³ molecules

8.1 mol × 6.022×10²³ molecules / 1 mol

48.7×10²³ molecules

4.87×10²⁴ molecules

have a great day because if you dont you and i will be sad
