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.
The molar mass constant is used to convert mass to moles
Answer:
The correct answer is 930 grams platelets.
Explanation:
The volume of blood given is 1.89 pints. Total number of gallons in 1.89 pints is,
= 1.89/8 = 0.236 gallon
1 gallon comprise = 3.785 L
So, 0.236 gallon comprise = 0.236 * 3.785 L = 0.89 L
As mentioned that 1 Liter of blood comprise 1.04 kilograms of platelets. Therefore, 0.89 L of blood will contain = 1.04 * 0.89 = 0.93 Kg platelets
1 Kg contain 1000 grams. So, number of platelets in grams will be,
= 1000 * 0.93 = 930 grams platelets.
The net ionic equation may be obtained from the reaction equation as follows:
HCl in solution is: H⁺ + Cl⁻
KOH in solution is: K⁺ + OH⁻
KCl in solution is: K⁺ + Cl⁻
H⁺ + Cl⁻ + K⁺ + OH⁻ → K⁺ + Cl⁻ + H₂O
Cancelling terms that are repeated on both sides,
H⁺ + OH⁻ → H₂O
This is the net ionic equation. Moreover, this equation holds true for all neutralization reactions.
