A CHEMIST measures 340 grams of sodium acetate. to convert the measurement to kilograms the chemist should multiply 340 by

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

Is this correct if not can u correct me

How many moles of kci are produced from 2.50 moles k
