The molar mass of kcl is 74.55 g/mol. if 8.45 g kcl are dissolved in 0.750 l of solution, what is the molarity of the solution?
0.113 m
0.151 m
6.62 m
11.3 m

Moles of KCl = 8.45/74.55 = 0.1133moles. Molarity = moles of KCl/ volume of solution in litres = 0.1133/0.75 = 0.151M.

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
