Question
I need help with #1 part e. What is the molar mass of the metal? Also please explain. I cannot find how to anywhere.
Experiment 14 Advance Study Assignment: Heat Effects and Calorimetry 1. A metal sample weighing 147.90 g and at a temperature of 99.5°C was placed in 49.73 g of water in a calo- rimeter at 23.0°C.
