What is the mass, in grams, of a sample of 1.72 × 1023 atoms of potassium (k)? show your work or explain the steps that you used to determine your answer.

Esure to answer all parts. the equilibrium constant for the reaction ni2+(aq) + 6 nh3(aq) ⇌ ni(nh3)6 2+(aq) is kf = 5.6 × 108 at 25°c. (a) what is δg o at this temperature? (b) if standard-state concentrations of reactants and products are mixed, in which direction does the reaction proceed? (c) determine δg when [ni(nh3)62+] = 0.010 m, [ni2+] = 0.0010 m, and [nh3] = 0.0050 m. in which direction will the reaction proceed to achieve equilibrium? (a) × 10 j/mol (enter your answer in scientific notation.) (b) to the right. to the left. (c) × 10 j/mol (enter your answer in scientific notation.) to the right. to the left.
