Question

If 6.5 L of water is added to 4.5 L of a 2.8 M Ca(OH)2 solution, what is the molarity of the new solution?

0.25 M
0.62 M
1.1 M
1.9 M

Answer 1

@Somy

Answer 2

write a balanced reaction

Answer 3

wait sorry
it looks like dilution

Answer 4

\( C_1 \times V_1\) = \( C_2 \times V_2\)

Answer 5

what is the C and V stand for?

Answer 6

C= molarity
V= volume

Answer 7

i got 1.1M?

Answer 8

how?

Answer 9

\(C_1 \times 6.5L\) = \(2.8M \times 4.5L\)

Answer 10

1. M = 12.6/(6.5+4.5)
2. M = 12.6/11
3. M = 1.145

Answer 11

you should rearrange the formula so you know what your are solving for.... it should look like this....
