Procaine hydrochloride (MW = 273) is a 2-ion electrolyte, dissociating 80%. Calculate its dissociation factor. Round to tenths p
Inga [223]

Answer:

Dissociation factor = 1.8

Explanation:

Data provided in the question:

Molecular weight of the Procaine hydrochloride = 273

Number of ions contained, n = 2

Fraction Dissociating, α = 80% = 0.8

Now,

the  dissociation factor 'i' is given as:

i = 1 + α × ( n - 1 )

on substituting the respective values, we get

i = 1 + 0.8 × ( 2 - 1 )

or

i = 1 + ( 0.8 × 1 )

or

i = 1.8

Lead has a density of 11.3 g/cm3 . what is the volume of a 15.1 g block of lead?
natita [175]
Hey there:

density = 11.3 g/cm³

mass = 15,1 g

Therefore: 

D = m / V

11.3 = 15.1 / V

V = 15.1 / 11.3

V = 1.336 cm³

for the given reaction, what volume of o2 would be required to react with 4.8 l of co , measured at the same temperature and pre
SVEN [57.7K]

We can see that 2 moles of The no react with 1 mole of O2 using this equation. 4.8 L NO x 1 L O2 / 2 L NO = 2.4 L of O2 are needed at constant pressure and temperature.

What is an example of pressure?

One can see a simple illustration of pressure by using a knife against a few fruit. If you press the flat side of the knife against the fruit, the top won't be cut. The force is spread more than a wide area (low pressure).

What are different types of pressure?

The physical pressure exerted to an object is referred to as pressure. Per unit area, a parallel force is applied to the surface of the objects. F/A (Force per Area) is the basic formula for pressure.
