Answer: 0.4578 g
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 25.0 ml
Thus 0.4578 g of nickel(II) nitrate is to be dissolved in 25.0 mL of 0.100 M solution.
Sp3. I just took a quiz exact same question and the answer was that I don't know how to get it sorry.
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.
