Un iceberg (densità ghiaccio = 920 kg/m3) ha un volume di 1500 m3 e galleggia nell’oceano (densità acqua salata = 1030 kg/m3).
a) Calcola la massa dell’iceberg b) Calcola la % di volume immerso. HELP!

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
