2.) Average atomic mass =Σ (abundance x molar mass) /100 = (12.64 x 302.04 + 18.23 x 304.12 + 69.13 x 305.03) /100 =304.486 u(Dalton) . This is avg atomic mass.

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a ∆g of -100 kcal/mol. if you double the amou

Debora [2.8K]

The doubling the amount will change the gibbs free energy as it is an extensive property which depends upon the the amount of the substance

However as asked in question the DeltaG has unit of kcal /mol

So we have already defined the amount of substance to be one mole this means the value per mole will be same irrespective of the amount taken as we are reporting it for a fixed one mole of a substance

Hence answer is

-100 kcal/mol
