What is the mass in grams of precipitate formed when 250.0 mL of
0.100 M ZnCl2 is mixed with excess
KOH in the following chemical
reaction?
ZnCI2 (aq) + 2 KOH (aq) → Zn(OH)2 (s)
+ 2 KCl (aq)

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

☆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
