Answer:
The long form version is too wide to easily fit on a computer screen or sheet of paper
Explanation:
Answer:
The rms speed of its molecules becomes. (T) has become four times. Therefore, v_(rms) will become two times,...
If the concentration of cholesterol is 238mg/100ml:
238 mg ==> 100ml
2380 mg (or 2.38g) ==> 1000ml (1L)
So the concentration will be 2.38 g/L of cholesterol.
if the volume is 5.2 L, the total grams of cholesterol would be :
m = C . V = 2.38g/L * 5.2 L = 12.376 grams of cholesterol.
Answer: a. atominc number= protons= 33
neutrons= mass- atominc number
80-33= 47 neutrons
b.35 protons
46 neutrons
hope this helps
A greater volume of acid will be needed to neutralize the sodium hydroxide thereby making the calculated concentration of acid for the second trial to decrease.
Titration is usually a way of determining the concentration of an unknown solution by accurately measuring the volume of a known solution that reacts completely with the unknown solution.
The point when reaction is completed is indicated by the end point of the reaction. If more base (sodium hydroxide) is added to the flask, then more volume of acid will be needed to neutralize it thereby making the calculated concentration of acid for the second trial to decrease.
