Calculate the number of moles of sodium stearate in a single layer.

Calculate the number of moles of sodium stearate in a single layer. To do this, first take the number of drops used to achieve the monolayer (1 drop) and convert it to mL using the calibrated number of drops per mL. Then multiply the number of grams of sodium stearate per milliliter of solution. Finally, convert to moles through the molar mass of sodium stearate. HINT: The molar mass of sodium stearate is 296.4 g/mol.

how would I solve this? its one gram of sodium stearate and 22.5 calibrated drops
