How many moles are in 1.29x10^24 hydrogen atoms in HF
Nonamiya [84]
We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules.

Thus,  6.022 X 10^23 atoms = 1 mole
Therefore, 1.29x10^24 = \frac{1.29X10^2^4}{6.022X10^2^3}
                                     = 2.14

Thus, 2.14 moles<span> are present in 1.29x10^24 hydrogen atoms in HF.</span>

For the diprotic weak acid h2a, ka1 = 3.2 × 10-6 and ka2 = 6.1 × 10-9. what is the ph of a 0.0650 m solution of h2a? what are th
Stolb23 [73]
Given:

Diprotic weak acid H2A:
 
Ka1 = 3.2 x 10^-6
Ka2 = 6.1 x 10^-9. 
Concentration = 0.0650 m 

Balanced chemical equation:

H2A ===> 2H+  + A2- 
0.0650       0        0
-x                2x       x
------------------------------
0.065 - x     2x      x

ka1 = 3.2 x 10^-6 = [2x]^2 * [x] / (0.065 - x)

solve for x and determine the concentration at equilibrium.

This gas law works only if temperature is recorded in ———— units
Vsevolod [243]

Answer:

Kelvin

Explanation:

  • Gas laws re the laws that relates properties of gases such as pressure, temperature and volume at different conditions.
  • Gas laws includes, Boyle's law, Charles law, grahams law and pressure law among others.
  • Temperature is one of the quantity of gases explained by gas laws. For gas laws to work, temperature should always be in Kelvin. Therefore, when given temperature in degrees, it is converted to Kelvin by adding 273, that is °C + 273 = K.
