How many sucrose molecules are in 3.0 moles of sucrose scientific

             1.80 × 10²⁴ Molecules of Sucrose

Solution:

Number of Moles and Number of Particles (molecules in given case) are related to each other as,

                  Moles  =  Number of Molecules ÷ 6.022 × 10²³

Solving for Number of Molecules,

                  Number of Molecules  =  Moles × 6.022 × 10²³

Data Given;
                     Moles  =  3 moles

Putting values in eq,

                 Number of Molecules  =  3 mol × 6.022 × 10²³

                 Number of Molecules  =  1.80 × 10²⁴ Molecules

Yes you are correct use the scientific method

It conforms what ever surface its in.
