An individual suffering from a high cholesterol level in her blood. if the total blood volume of the individual is 5.2 l, how ma

ny grams of total blood cholesterol does the individual's body contain

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 pressure of 8.4 of nitrogen gas in a flexible container is decreased to one-half its original size
lutik1710 [3]

The new volume is 33.6 L.

<h3>What is volume?</h3>

Volume can be described as a measure of occupied three-dimensional space.

From the question above, we obtain the following data:

Initial volume (V1) = 8.40 L L

Initial pressure (P1) = P

Initial temperature (T1) = T

Final pressure (P2) = one-half the original pressure = ½P

Final temperature (T2) = double the original temperature = 2T

Final volume (V2) = what?

The new volume can be obtained by using the universal gas law;

P1V1/ T1 = P2V2 /T2

P × 8.40 / T = ½P × V2 /2T

P × 8.40 / T = P × Volume 2 / 4T

Cross multiply

T × P × Volume 2 = P × 8.40 × 4T

Divide both side by T × P

Volume 2 = (P × 8.40 × 4T) /T × P

Volume 2 = 8.40 × 4

Volume 2 = 33.6 L

Thus, the new volume of the gas is 33.6 L.

A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The re
Arte-miy333 [17]

The mass of nickel is 36.5g metal.

Ni+2AgNO3 → Ni(NO3)2+2Ag

21.5g Ni / 58.69g = 0.366mol Ni

Ag = 107.87

N i= 58.69

But, 2molAg per 1 mol Ni, so, change in mass is more like...

Twice as many moles Ag as Ni, and then the mass relationship is 107.87g Ag / 58.69, but due to the 2Ag: 1Ni mol ratio, the change in mass is like:

107.87(2) / 58.69 = 3.68 times increase

So, the final mass of Ag is 3.68x, and the change in mass of Ni is x

36.5=(21.5-x)+(3.68x)

Solve for x

x=5.597

3.68x=g Ag

3.68(5.597)=20.59

21.5 - x = g Ni after reaction

21.5 - 5.597 = 15.903g Ni

20.59g Ag + 15.903g Ni = 36.5g metal

The mass of nickel is 36.5g metal.

Which of the following is an oxidation-reduction reaction?
KiRa [710]

C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O

This is an oxidation-reduction reaction, because oxidation numbers of carbon and oxygen atoms are different than before reaction.
