Hypertonic" is the one among the following choices given in the question that is a solution used for salad dressing.
Explanation:
A hypertonic solution is a special type of solution that has a greater concentration of solutes on the outside of a cell when associated with the inside of a cell.as a result, water inside the cell will move outwards to attain equilibrium, creating the cell to shrink.
Answer:
Thus,there are 0.2 mole in 8 g of calcium.
Answer: B
Molarity is defined as M=(m/mw)/L solution where M is molarity, m is weight, mw is molar weight and L is liters.
First we plug in the mass, which is 5, then divide by the molar weight of 39.9969 which can just be rounded to 40.
Then we convert 750mL to liters which would be 0.75 liters. The root "milli" is x10-3, therefore we convert it to become 0.75L.
Now we just solve the equation, 5/40/0.75 is 0.166 repeating decimal, or just 0.167 rounding to three significant digits.
