(STEP 5: IRON) Tare the balance. Put calorimeter (no lid) on the balance.
Measure the mass to the nearest 0.01 g
12.42 g

Use a graduated cylinder to add approximately 40 mL of
water to the calorimeter. Measure the mass of the
calorimeter (no lid) and water to the nearest 0.01 g.
52.66 g

Subtract to find the mass of the water. 40.24
g
