How many moles of glucose (c6h12o6) represent 3.0 x 1024 molecules of glucose?

Avagadros number states that 1 mol of any substance consists of 6.022 x 10²³ units. 
1 mol of glucose is made of 6.022 x 10²³ molecules of glucose. 
Therefore if 6.022 x 10²³ molecules make 1 mol
then 3.0 x 10²⁴ molecules of glucose make up - 1/(6.022 x 10²³) x 3.0 x 10²⁴
Therefore number of glucose moles are - 5.0 moles of glucose
