How many moles of Ca(NO3)2 are needed to make 1.50 L of a 6.00 molar solution?

9.0 moles Ca(NO₃)₂

Explanation:

from definition of Molarity = moles of solute / volume of solution in liters

=> moles = Molarity x Volume(L) = 6.00 molar x 1.5 liters = 9.0 moles Ca(NO₃)₂

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
