10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL
.9% NACL = 9g/1000mL, Ergo = 9000mg NaCl
Now we have to figure out how many mEqs of each salt we have.
MW of NaCl = 58.5
MW of KCl = 74.5
So, in moles, we have:
1500 KCl / 74.5 = 20.13 mmol KCl
9000 NaCl / 58.5 = 153.85mmol NaCl
Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL.
So, just add the two together, 20.13 + 153.85 = 174-ish.
Area = Length x Width
Given that the area is 30 cm² and Length = 5 cm, find width:
30 = 5 x width
width = 30 ÷ 5 = 6cm
Answer: The width is 6 cm
Harry's trainer recommends Harry drink
8*(8 oz) = 64 oz
of water per day.
A pint is 16 oz, so this amounts to
(64 oz)*(1 pt)/(16 oz) = 4 pt
of water per day.
By drinking 3 full bottles of water, Harry drank
3*(1 1/4 pt) = 3 3/4 pt
of water.
This amount of water (3 3/4 pt) is less than the 4 pt recommended by the trainer. Harry's claim that he drank the full amount is not true.
After carefully looking over my notes and gathering all my knowledge of college mathematics, I can honestly say that I have no idea what the answer is.
