Assignment:
Q1. What is the percent of CdSO4 by mass in a 1.0 molal aqueous solution?
Q2. Calculate the amount of heat that must be absorbed by 10.0 gram of ice at -20 C to convert it to gaseous water at 110 C. Given:
Specific heat ice = 2.1 Joule/gram
water = 4.184 Joule/gram
steam = 1.84 Joule/gram
change in heat fusion =6.01 K Joule/mol H2O
change in heat vapor= 40.7 K Joule/mol H2O
Provide complete and step by step solution for the question and show calculations and use formulas.
