The molarity of a solution in which 55. 49 g of calcium chloride is dissolved in enough water to make 500. ml of solution is 1M.
<h3>What is molarity? </h3>
It is defined as number of moles of solute divided by volume of solution.
Given,
Mass of CaCl2 =55.49g
Molar mass of CaCl2 =40+35+35=110g
Mole= given mass/ molar mass
= 55.49/110=0.50mol.
Now, putting all values we get the molarity
Molarity =0.5×1000/500=1M
Thus, the molarity of given solution is 1M.

I think it's the last one
(and I'm so sorry if I'm wrong)
Answer:
Explanation:
585.2 meters per minute in 32 feet per second To convert any value in feet per second to meters per minute, just multiply the value in feet per second by the conversion factor 18.288. So, 32 feet per second times 18.288 is equal to 585.2 m/min.
E should be correct.
The color may change, precipitation may occur, bubbles may form, gas forms, and the temperature changes.
Mark if correct please!
