Non of them seem right... but I think C could be correct cause it definitely cant be A.
Hazardous coolants in refrigeration units where replaced;) hope it helped have a good day!
Answer:
The answer is B i think, sorry if im wrong
Explanation:
Molarity = Moles / Liters! So in this instance, if you have 0.45 moles of NaCl, and we convert 300.0 mL to 0.3 L, we would plug in M = 0.45/0.3. The answer would be 1.5 M NaCl!
Use dimensional analysis.


Now you try converting moles to grams. All you have to do is start with MOLES (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!
