# Chemical Reaction in a Calorimeter## Problem StatementA mass of 4.165 g of NaOH(s) is mixed with 100.0 mL of H₂O in a Styrofoam calorimeter. Calculate the moles of NaOH(s) added to the calorimeter. The molar mass of NaOH is 40.00 g/mol and H₂O is 18.016 g/mol. Report your value to the correct number of significant figures. Do not include the units with the value you input.## ExplanationThis experiment involves dissolving solid sodium hydroxide (NaOH) in water and measuring the heat absorbed or released using a calorimeter. The main objective is to find out how many moles of NaOH are present initially. ### Key Steps:- Determine the moles of NaOH by using its mass and molar mass.- Use the formula: \[ \text{Moles of NaOH} = \frac{\text{Mass of NaOH (g)}}{\text{Molar Mass of NaOH (g/mol)}} \]- Ensure your final answer is given to the correct significant figures as instructed.
