I need help with these three questions, please!

(1) If a 46.0 g sample of the liquid iodobenzene has a volume of 25.1 mL, what is the specific gravity of the compound? Take the density of water to be 1.00 g/mL. specific gravity = (2) The liquid iodobenzene is insoluble in water. If approximately equal volumes of water and iodobenzene were mixed in a separatory funnel, would the water layer end up on the top or on the bottom? Consider the following operations on the number 2.42 x 10-2 Without using a calculator, decide which would give a significantly smaller value than 2.42 x 10-2, which would give a significantly larger value, or which would give essentially the same value. larger smaller V 2.42 x 10-2 + 8.19 x 105 2.42 x 10-2 8.19 x 105 2.42 x 10 x 8.19 x 105 2.42 x 10 -2 8.19 x 105 -2 larger larger Submit Answer Retry Entire Group 9 more group attempts remaining
