Question

2.
20 ml of 0.5 M HCl is mixed with 30 ml of 0.3 M
HCl the molarity of resulting solution is
​

Answer 1

formul@ is (m1v1 + m2v2)/(v1 + v2)

so it will be equal to 0.019/0.05

=1.9/5

=0.38 M

Answer 2

Answer:

Explanation:formula is

(M1×v1)+(m2×v2)=m3 (v1+v2)

(0.5×2.20)+(0.3×30)=m3 (30+2.20)

1.1+9=m3 (32.2)

10.1÷32.2=m3

0.31 = m3

Answer = 0.31 total molarity
