Acertain molecular compound m has a solubility in acetone of 0.737g/ml at 10.°ccalculate the mass of m that's dissolved in 9.0l of a saturated solution of m in acetone at this temperature. be sure your answer has the correct unit symbol and number of significant digits.

6633 grams of M are dissolved in 9L

Explanation:

If the compound M has a solubility in acetone of 0.737 g/mL, means that in 1 mLof solution, 0.737 grams of solute is dissolved.

Let's make a rule of three:

9 L = 9000 mL

In 1 mL ___ 0.737 g of M is dissolved

In 9000 mL ___ (9000 . 0.737) /1 = 6633 grams

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

they are all solids.
