To how many significant figures should each answer be rounded? Equation A: (6.626× 10−34 J⋅s)(2.9979× 108 m/s)4.290×10−7 m=4.630322937063×10−19 J(unrounded) After rounding, the answer to equation A should have *2 significant figures. *1 significant figure. *4 significant figures. *3 significant figures. *5 significant figures. Equation B: (6.022× 1023 atoms/mol)(0.795 g)20.18 g/mol=2.372×1022 atoms(unrounded) After rounding, the answer to equation B should have *1 significant figure. *3 significant figures. *5 significant figures. *2 significant figures. *4 significant figures.
