Three different people weigh a standard mass of 2.00g on the same balance. Each person obtains a reading of 7.32g for the mass of the standard. The results imply that the balance that was used is ___?

The answer is 1.82 j/g°c

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -

Iam pretty sure that the answer is d
