Answer:
124.56 moles of Hydrogen atoms.
Explanation:
We'll begin by calculating the number of moles of ethane that contains 1.25×10²⁵ molecules. This can be obtained as follow:
From Avogadro's hypothesis, 1 mole of any substance contains 6.02x10²³ molecules. This implies that 1 mole of ethane also contains 6.02x10²³ molecules.
Thus, 6.02x10²³ molecules are present in 1 mole of ethane.
Therefore, 1.25×10²⁵ molecules are present in = 1.25×10²⁵/6.02x10²³ = 20.76
Therefore, 20.76 moles of ethane contains 1.25×10²⁵ molecules.
Finally, we shall determine the number of mole of Hydrogen in 20.76 moles of ethane. This can be obtained as follow:
Ethane has formula as C2H6.
From the formula, 1 mole of ethane, C2H6 contains 6 moles of Hydrogen atoms.
Therefore, 20.76 moles of ethane will contain = 20.76 × 6 = 124.56 moles of Hydrogen atoms.
Therefore, 1.25×10²⁵ molecules of ethane contains 124.56 moles of Hydrogen atoms.
Answer:
Most indoor growers will want to aim for 50-70% relative humidity, although 60-80% is usually tolerable.
Explanation:
Answer:
Calculated molarity of acid is higher than the actual concentration.
Explanation:
For an acid-base titration, the following equation is obeyed for calculation-
where, C represents concentration and V represents volume.
So, 
Here, 
and 
are constants.
Actual volume of base added from burette is lesser than the volume used (based on assumption) for calculation of concentration of acid.
So, actual value of 
is lesser. Hence calculated concentration or molarity of acid is higher than the actual concentration.
The number of protons and neutrons are approximately equal to the atomic mass
The solubility of the compound is obtained as 9.5 * 10^-14 M.
<h3>What is the solubility product?</h3>
The solubility product refers to the equilibrium constant that shows the extent to which a thing is soluble in water, Now we can write the solubility product as;
Ksp = [Hg^2+] [2OH^-]^2
Let [Hg^2+] = [OH^-] = x
Then I can write;
Ksp = x * (2x)^2
Ksp = 4x^3
When x = solubility
x = ∛Ksp/4
Ksp = 3.60×10^−26
x = ∛ 3.60×10^−26/4
x = 9.5 * 10^-14 M
