PLEASE HELP! 1. Describe the relationship between the mole and molar mass.
2. describe the process for converting between moles and molar mass.
3. Explain how percent composition is calculated and why is it important in the determination of empirical formula.
4. Analyze the role coefficients in a chemical reaction play in stoichiometry
Explain what a limiting reactant is and describe the process to determine the limiting reactant in the example listed below:
5. Given 3.4 grams of x element with a molar mass of 24 g/mol and 4.2 grams of y element with a molar mass of 35 g/mol. How much of compound xy2 can be generated?
x + 2y -> xy2
6. Explain where you would find the actual yield and the theoretical yield needed to calculate the percent yield of a reaction. Is the answer listed above the theoretical or actual yield?
