200.0 mL OF A 5.10 M solution are diluted to 500.0 mL. What is the concentration of the resulting solution? *
erastova [34]

Answer:

Concentration of the resulting solution = 2.04 M

Explanation:

<u>Data:</u>

M1 = 5.10 M

V1 = 200.0 mL

V2 = 500.0 mL

M2 = ?

By modifying the volume of solution, keeping the amount of solute constant, the concentration changes. To perform the calculations, the equation will be:

M1*V1=M2*V2

Where M1 is the initial concentration of the solution, M2 the final concentration and V is the value of the volumes of the initial and final solution.

Clearing the value of M2 from the equation and replacing the values ​​we have:

M2=\frac{M1*V1}{V2} =\frac{5.10M*200mL}{500mL} =2.04M

1. Alexa and her family travelled 5 hours south east on 1-45 to crystal
Gre4nikov [31]

Answer:

Average speed  = 68 mph

Explanation:

Given that,

Total distance traveled by the family, d = 340 miles

The family traveled 5 hours southeast.

We need to find her average speed. The speed of an object is given by the total distance covered divided by time taken. So,

v=\dfrac{d}{t}

Put all the values,

v=\dfrac{340}{5}\\\\v=68\ mph

So, her average speed is equal to 68 mph.
