Josh prepares a solution by mixing sodium nitrate and water. to calculate the molarity of the solution, josh should calculate the moles of which substance, and why?
i believe that the most scientific questions out of the ones asked is the first one: what is the age of earth?
plz mark brainliest if u can
first thing you need to do is write the chemical equation and check to see if it is balancedal(no₃)₃ + nacl ⇒ nano₃ + alcl₃the left hand side requires 3 more chloride ions, while the right hand side needs 3 nitrate ions to be balanced. add a coefficient of 3 on nacl and nano₃ to get a balanced equation.al(no₃)₃ + 3nacl ⇒ 3nano₃ + alcl₃the ratio of al(no₃)₃: nacl is 1: 3, which means 1 mol of al(no₃)₃ reacts with 3 moles of nacl ˣ =clearly, nacl is the limiting reactant since according to the ratio 1: 3, 4 mol al(no₃)₃ should react with 12 mol nacl, but the reaction data has 9 mol of nacl available. use the limiting reactant moles to find the product nano₃ formed.the molecular weight of nano₃ is 84.9965 g/mol and thus mass of nano₃ formed is mass = (9 moles nano₃)(84.9965 g/mol nano₃)= 764.97g
