How many molecules are present in 1 teaspoon of sucrose if its mass is 4.10g? show your work

4.10 g C12H22O11 * (1 mol / 342.2965 g) * (6.022x10^23 / 1 mol) = 7.2107077x10^21 molecules = 7.21x10^21 molecules

Convert grams to moles using the molar mass (g/mol).

Use Avogadro's constant (6.022x10^23) to get the quantity of molecules from the amount of moles.

Revise answer to have the correct number of significant figures (the smallest amount of digits in any number in the problem is the amount of significant figures your answer should have).
