Question

How many molecules of glucose are in 1,456 grams of glucose?

Answer 1

Answer:

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
