Volume=25L
Temperature=5°C
Pressure=89.9kPa

Now

$\\ \rm\rightarrowtail PV=nRT$

$\\ \rm\rightarrowtail n=\dfrac{PV}{RT}$

$\\ \rm\rightarrowtail n=\dfrac{89.9(25)}{5R}$

$\\ \rm\rightarrowtail n=89.9(5)/R$

$\\ \rm\rightarrowtail n=449.5/R mol$

umka21 [38]

The reaction is
C₂H₄ + O₂ → CO₂ + H₂O

To balance the equation, both side have same number of elements. Here,

In left hand side has in right hand side has

4 H atoms 2 H atoms

2 C atoms 1 C atom

2 O atoms 3 O atoms

First, we have to balance number of C atoms and number of H atoms in both side.
To balance C atoms, '2' should be added before CO₂ and to balance H atoms, '2' should be added before H₂O.
Then number of oxygen atoms is 2 x 2 + 2 = 6 in right hand side. So, 3 should be added before O₂ in left hand side.
After balancing the equation should be,

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

An average human being has about 5.0 L of blood in his or her body. If an average person were to eat 37.7 g of sugar (sucrose, ,

Viktor [21]

Answer: 0.0220275 M

Explanation:

So, we are given the following data or parameters which are going to help in solving this particular Question/problem.

=> Averagely, we have the volume = 5.0 L of blood in human body .

=> Mass of sugar eaten = 37.7 g of sugar (sucrose, 342.30 g/mol).

Therefore, the molarity of the blood sugar change can be calculated as below:

The molarity of the blood sugar change = (1/ volume) × mass/molar mass.
