13. 250ml 1mM CuSO4
MW = 159.61gm
1Molar = 1M = 159.61gm in 1000ml
1mM = 159.61gm / 1000 in 1000ml =0.159gm in 1000ml = 0.03975gm in 250ml
14. 500ml 0.25M NaCl
MW = 58.44
1M= 58.44gm / 1000ml
0.25M = (58.44gm x 0.25) in 1000ml = 14.61gm in 1000ml = 7.305gm in 500ml
15. 100ml 20microM CaCl
MW = 111.0gm
1M = 111gm / 1000ml
20microM =[ (20 x 10-6) x111 ] in 1000ml = 2220 x 10-6 gm / 1000ml
= 222 x10-6 gm in 100ml = .00222gm in 100ml
16. 10ml 1M Na2SO4
MW = 322.04gm
1M = 322.04gm in 1000ml = 32.2gm in 10ml
17. 50ml of 3:2:1 ethylene: chloroform: isoamyl alcohol
the total of dividing portions or partitions = 3+2+1 = 6
So 3 portions of 6 should be ethylene in 50 ml of mixture. That means, 3 portion comes as (3 / 6) x 100 = 25ml
2portion chloroform means (2 / 6) x 50 = 16.66ml
1portion isoamyl alcohol means (1 / 6) x 50 = 8.33ml
ethylene : chloroform : isoamyl alcohol = 25ml : 16.66ml : 8.33ml
18. 10ml 1:3 NaCl: water
(1/4)x10= 2.5ml NaCl and (3/4) x10= 7.5ml water
19. Convert 5ppm to mg/ml
1ppm = 1milligram / Liter = 1mg / L
5ppm= 5mg / L = 5mg / 1000ml = 0.005mg / 1ml
20. Convert 5ppm to microgram / L
5ppm = 5mg / L = 5 x 1000 microgram / L = 5000microgram /L
21. Convert 5ppm to microliter / ml (I doubt this is possible since ppm is the unit of concentration 'microgram' but not the volume 'microliter')
5ppm = 5mg / 1000ml= 5000microgram / 1000ml = 5microgram / ml
22. Convert 500ppm to ml / L (I doubt this also is possible since it can be converted to milligram/L, but not ml / L)
500ppm = 500mg / L
23. 300ppb Cadmium
1ppm = 1000ppb So 1ppb = 0.001ppm
300ppb = 300x 0.001ppm = 0.3ppm = 0.3mg / L
