The answer is the second option. The given conversion from L to dm3 is actually confusing. Just remember that 1 L = 1000 cm3.
Simply, multiply 2.6 by 1000 and we get 2600 cm. Converting this to scientific notation, we get the answer:
2.6 x 10^3 cm3

200.0 mL of a 0.845 M solution of KCl is diluted to 600.0 mL. What is the new concentration of the solution?

Ipatiy [6.2K]

M be molar concentration
V be volume

So

M1=0.845M
V1=200mL=0.2L
V2=0.6L
M2=?

$\\ \tt\rightarrowtail M1V1=M2V2$

$\\ \tt\rightarrowtail 0.845(0.2)=0.6M2$

$\\ \tt\rightarrowtail 0.169=0.6M2$

$\\ \tt\rightarrowtail M2=0.281M$
