plz mark me as brainleist
Step-by-step explanation:
Conc H2SO4 36N is 18M sulphuric acid
We can use the formula:
m1v1 = m2v2
Where
m1 = initial molarity
v1 = initial volume
m2 = final molarity
v2 = final volume
18 x 50 = m2 x (50 + 50)
900 = 100m2
m2 = 900/100
m2 = 9
The molarity of the solution is 9M
