1) 1ml of 18.13mM diluted to 100ml 2) 2ml of 18.13mM diluted to 100ml 2) 2ml of 18.13mM diluted to 100ml 3) 3ml of 18.13mM diluted to 100ml 3) 3ml of 18.13mM diluted to 100ml 4) 4ml of 18.13mM diluted to 100ml 4) 4ml of 18.13mM diluted to 100ml 5) 5ml of 18.13mM diluted to 100ml 5) 5ml of 18.13mM diluted to 100ml

Explanation / Answer

1) 1ml of 18.13mM diluted to 100ml

M1 = 18.13

V1 = 1ml

M2 = ?   

V2 = 100ml

M1 V1 = M2 V2

18.13 x 1 = M2 x 100

M2 = 0.1813 M

concentration = 0.1813 mM

2) 2ml of 18.13mM diluted to 100ml

2 x 18.13 = C x 100

concentration = 0.3626 mM

3) 3ml of 18.13mM diluted to 100ml

3 x 18.13 = 100 x C

C = 0.5439 mM

concentration = 0.5439 mM

4) 4ml of 18.13mM diluted to 100ml

4 x 18.13 = C x 100

C = 0.7252

concentration = 0.7252 mM

5) 5ml of 18.13mM diluted to 100ml

5 x 18.13 = C x 100

C = 0.9065 mM

concentration = 0.9065 mM
