Intravenous, or IV, solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into

or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100. mL of solution (sometimes referred to as 0.90 % m/v).
1. If the van't Hoff factor of NaCl is i = 1.8, what is the osmotic pressure of blood at body temperature, 37°C?

7 0

Answer:

7.055 atm

Explanation:

T = (273 + 37)K = <em>310K</em>

The ideal gas constant =<em> 0.0821</em>atm.L/mol.K

Concentration = (0.90g)*(1mol/58.4g/0.100mL) = 0.154mol/L

Molar mass= Concentration*i

Osmotic pressure = Molar mass *the ideal gas constant*T

OP = (0.154)*(1.8)*(0.0821)*(310) = 7.055 atm

Si se tiene 1mol de NO . cuantas moleculas de NO hay
kumpel [21]

if you have 1mol of NO. how many molecules of NO are there

Answer:

6.02 x 10²³ molecules

Explanation:

Given parameters:

Number of moles of NO = 1 mole

Unknown:

Number of molecules in NO;

Solution:

A mole of compound contains the Avogadro's number of particles.

  1 mole of a substance contains 6.02 x 10²³ molecules

So, 1 mole of NO contained 6.02 x 10²³ molecules

By means of a schematic diagram show how a bacteria cell applied to the region of a cowpea root can end up by becoming a nitrate
masya89 [10]

Answer:

Nitrifying bacterium such as nitrosomonas or nitrobacter, whe applied to the soil, convert free ammonia or nitrogen to nitrates through oxidation. They are a group of aerobic bacteria playing an important role in the nitrogen cycle as producers of energy from inorganic source.

The schematic diagram attached summaries the action of such bacteria.
