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.
35 miles per hour. 70/2=35, 140/4=35, 210/6=35, 280/8=35 :)
The answer would be (x-3y) (x-7y)
You have to group them together
the 2 answers are AB and DE
Answer:
-19
Step-by-step explanation:
she spent 12 and 7 dollars which are being subtracted from her budget, therefore there is a -19 dollars effect on her budget.
