Question

in a reaction 8.21 g of lead nitrate reacted with 9.26 g of potassium iodide. The products were 7.56 g of lead iodide and 10.02 g of potassium nitrate. Show that this observation is in the agreement with the law of conservation of mass.​

Answer 1

Explanation:

To prove that a given reaction show or obey the law of cons of mass , we need to prove that -

mass of reactants = mass of products

though in this question we are not getting exact values.. but by little approximation we get-

mass of reactants= 8.21+9.26=17.47g

mass of products=10.02+7.56=17.58g

hence we can prove law of conservation of mass
