Answer 3

use this concept :-
\[\large \bf M_iV_i=M_fV_f\]

Answer 4

where,
\[\large \bf M_i=1.5 M~;V_i=50~mL~;M_f=?;V_f=50+200=250~mL\]

Answer 5

plug into equation and solve for Mf

Answer 6

hope you understand. @Dedi

Answer 7

we do \[C _{1} * V _{1} = C _{2} * V _{2}\]
thene \[C _{2} = \frac{ C _{1} * V _{1} }{ V _{2} }\]
so \[C _{2} = \] 50*1.5 / 200+50
\[C _{2} = \] 0.3 M
