4. What mass of water would absorb 7.00 × 10² cal of heat if the temperature is increased from 35.0°C to 47.0°C? 5. A 4.00 g sample of a salt is dissolved in 50.0 g of water at 25.00°C. If the specific heat of the resulting solution is 0.970 cal/g °C and if the final temperature of the solution is 34.00°C, calculate the heat of solution of the salt in cal/g.
