D. square planar. E. trigonal planar 80. Which of the following has the strongest repulsion A. lone-pair vs. bond-pair repulsion B. bone-pair vs. bond-pair repulsion C. lone-pair vs. lone-pair repulsion D. lone-pair vs. lone-pair repulsion E. All of them have the same repulsion 81. If 0.274 moles of a substance weighs 62.5 g, what is the molar mass of the substance, in units of g/mol? A) 2.28 times 10^2 g/mol B) 1.71 times 10^1 g/mol C) 4.38 times 10^-3 g/mol D) 2.17 times 10^2 g/mol E) 0.02 times 10^23 g/molExplanation / Answer
answer 78
option D is correct
answer 79
option A is correct
answer 80
option C is correct LP-LP repulsion
answer 81
molar mass = mass / moles
molar mass = 62.5 / .274 option A is correct .....
