in an experiment to determine the solubility of potassium chloride, it was found that 27.40g of the saturated solution at 30oC contained 7.40g . calculate the mass of water in 27.40g of the saturated solution at 30oC of the salt.

have a great day because if you dont you and i will be sad

that's what i got you can count the number of atoms

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.

it is a solid
