What mass of silver nitrate (agno3) is required to prepare 400 g of a 3.50% solution of agno3?

mass % = mass of the solute/   mass of the solvent

let mass of the solute= y

mass of solvent= 400g

%mass= 3.50 %  into fraction= 3.5/100

=3.5/100= y/400

multiply both side by 400

y= 14 grams

6.4 cm (max) - 25 cm (min)

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.
