In this question, magnesium, it reacts with hydrochloric acid.
00:07
So in the single displacement reaction, so mgcl2 plus h2.
00:16
So it is aquaous, so it is also aquaise and magnesium solid.
00:25
So if 420 ml of 5 molar h .l, it reacts with excess of magnesium.
00:33
So how many moles of hcl are consumed consumed so how many grams of mgcl 2 will form? okay, so here the reaction magnesium reacts with 2 hcl this is the given reaction mgcl2 acquies plus hydrogen gas so 420 ml of 5 molar h .c .l react.
01:12
So, molarity.
01:14
So we know that molarity, molarity is equal to moles per volume.
01:23
Mularity is equal to, molarity is equal to moles per volume per liter.
01:36
So here, 1ml is equal to 10 to the power of minus 3 liters.
01:41
So, so, so, moles of h .c .l...
