Aron is training for a 10 km marathon swim in 19 weeks.  Each week, his training plan includes a long distance swim.  In week six, Aron swam a total of 18.75 km.  In week ten, Aron swam a total of 36.25 km.  Each week, Aron increased the distance he swam following an arithmetic sequence until the final week.  In the last week, Aron only swam 5 km in order to save energy for the race.

A 70.0g sample of water at 95.00C is mixed with 50.0g of water at 135C. Calculate the final tempreture of the mixture assuming no heat loss to the surroundings. Remember that the heat gained by the cooler water is equal to the heat lost by the warmer water.

calculate the enthalphy of solution of cacl29(aq) if when 11.0g of cacl2 is added to water to make 125ml of solution the tempreture increases from 25.0 to 39.2(-75.0kj/mol)
