What is the fraction of the hydrogen atom's volume that is occupied by the nucleus? the bohr radius is 0.529×10−10m?
Arturiano [62]

Volume of a sphere = 4/3 x pi x r^3

When put a fraction of volume constant 4/3 x pi cancels out.

So only cube of radii remains.

Radius of proton = 10^-15 m (Fact; remember it)

Radius of total Hydrogen atom = 0.529 × 10^−10 m

Fraction of Volumes : R'^3/R^3 = (R/R)^3

Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =

6.755 x 10^-15

Given: There are 39.95 grams of Argon (39.95 g/1 mole) and one mole has a volume of 22.4 Liters (1 mole/22.4 L). What is the vol
marta [7]

Answer:

V_2=19.23L

Explanation:

Hello,

In this case, by using the Avogadro's law which allows us to understand the volume-moles behavior as a directly proportional relationship:

\frac{V_2}{n_2} =\frac{V_1}{n_1}

We can compute the volume of 34.3 g of argon by representing it in mole as shown below:

n_1=1 mol\\\\n_2=34.3g*\frac{1mol}{39.95g} =0.859mol

Thus, we find:

V_2=\frac{V_1*n_2}{n_1}=\frac{22.4L*0.859mol}{1mol} \\\\V_2=19.23L

Best regards.
