Solve the all parts of given problem:
Problem: Suppose 12.2 g of oxygen (O2) is heated at constant atmospheric pressure from 25.3°C to 141°C.
Part A: How many moles of oxygen are present? (Take the molar mass of oxygen to be 32.0 g/mol)
Part B: How much energy is transferred to the oxygen as heat? (The molecules rotate but do not oscillate.)
Part C: What fraction of the heat is used to raise the internal energy of the oxygen?
I need tutor help to solve the above problem.
