Instead of grams, you need to convert into mol. This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that toge...
- The decomposition of calcium carbonate (CaCO3) can be represented as: CaCO3→CaO+CO2 3.Determine the molar masses: - Molar mass of CaCO3 = 100 g/mol - Molar mass of CaO = 56 g/mol 4.Calculate the amount of CaO produced:
The solubility of a certain salt in an aqueous solution in molar units can be determined by using the expression of the solubility product. Then, it can be converted into g/L with the help of the molar mass of the salt. Answer and Ex...
