Hey, buddy i solved your question just now so , here you can also check :)

From the formula ,Mf = M1V1 + M2V2/v1 + v2

Given ,
V1 = 750ml
M1= 0.5 M

V2 = 250ml
,M2 = 2M

=
$\frac{750 + \times 0.5 + 250 \times 2}{750 + 250} \\ = \frac{875}{1000} \\ = 0.875$

Answer = 0.875 M

Answer 2

From the formula ,Mf = M1V1 + M2V2/v1 + v2

Given ,
V1 = 750ml
M1= 0.5 M

V2 = 250ml
M2 = 2M
