How many molecules of sugar (sucrose) are there in 5g of sugar?

Answer 1

*Sucrose has a molecular formula of C₁₂H₂₂O₁₁ with a molar mass of 342.3 g/mol.

*The number of moles of sucrose in 5 g of sucrose is (5 g) / (342.3 g/mol) = 0.01461 mol.

*The number of molecules of sucrose is then calculated using Avogadro's number:

(0.01461 mol) x (6.022 x 10²³ molecules/mol) = 8.799 x 10²¹ molecules

I hope this helps!
