Question

How many moles of lead chloride will be formed from a reaction between 6.5 gram of pbo and 3.2 gram of HCL

Answer 1

Approx. 0.03 mol PbCl2Explanation:First of all, write out the reaction.PbO + 2HCl = PbCl2 + H2O(Don`t forget to correctly balance the reaction)6.5g PbO x 1mol PbO/223 g = 0.03 mol PbO3.2g HCl x 1mol HCl/36.5g = 0.088 mol HClFrom this, we can conclude that PbO is the limiting reactant/reagent. Therefore, we will use PbO to figure out the amount of moles of PbCl2.0.03 mol PbO x 1mol PbCl2/1molPbO = 0.03 mol PbO.
