The answer is b it will always be equal
The correct answer is C. Dr Smith, who measures 13.5 g/mL on e2020.
B. concentrated
A. is incorrect because it COULD be saturated. C. is incorrect because a large amount of salt is concentrated into a small amount of water, so it can't be diluted, relatively. D. is incorrect because it does not describe a solution's molality or molarity.
Hello friend, the answer would be 1609.34. Hope it helps. :) BTW, I've also double checked for you. :)
Answer:
2nd option
Explanation:
Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).
Given: concentration= 232g/ L
what we are trying to achieve is __mol/ L.
So in 1 litre, we have 232g of NaCl.
To convert mass to mole, we divide it by the Mr.
Given that the Mr is 58g/mol,
number of moles
= 232 ÷58
= 4
Thus, 1 litre has 4 moles of NaCl.
Therefore, the molarity is 4.0 mol/L.
