Question

Review Constants Periodic Table Part D A chemical reaction in which reactants A and B form the product C is studied in the laboratory. The researcher carries out the reaction with differing relative amounts of reactants and measures the amount of product produced. Examine the given tabulated data from the experiment and answer the questions. A is the limiting reactant in Experiments 2 and 3. Calculate the mass of B remaining after the reaction in Experiments 2 and 3 have gone to completion, given that the molar mass of A is 60.0 g/mol , the molar mass of B is 90.0 g/mol, and the molar ratio between the two is 2 mol A:1 mol B. Express your answer numerically in grams, separated by a comma.

Answer 1

I ZA & B C for EXP: 2 mass more of A = 6.04 A = 6.04 = 0.10 mass B = moles of B = 901 9,01 = 0.do go a mole of (given a reacts molar with more of ß ratio 2:1) react with 0.1 = 0.05 mole A will 0.1 mol of 0.1-0.05 = 0.05 0.05x90 = 4.5 gm remaining = a remaing = mol of B mass of 9.06 for Exp-3 mass of A = 9.06 moles of A = To = 0.15 for 0.15 mole of A, mole of B wad = 0.15 moo on B remaining = 0.1 0.075 = 0.025 Weight B remaining = 0.025 x 90 = 2.25gm Please Rate
