please help. with both questions. please use the correct significant digits

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 3.50kg of water at 30.4 "C. During the reactian 143 . kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath, You can assume the specific heat capacty of water under these conditions is 4.18 J'g 1, K - . Be sure your answer has the correct number of significant digits. A sample of an unknown compound is vaporized at 130 . C. The gas produced has a volume of 1430 , mL. at a pressure of 1.00 atm, and is weighs 1.30 g. Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Be sure your answer has the correct number of significant digits
