Sulfur has atomic mass of 32.06 so you divide 232 by 32.06 to get 7.24 mol using sig figs
answer= 7.24 mol of S

Answer:

7.235 mol of S are in the given sample

Explanation:

Number of mol calculated as follows:

Number of mol = amount in g / molar mass

Given that amount of sulfur = 232 grams.

Molar mass of sulfur = 32.065 g/ mol

Therefore the number of S is calculated as follows:

Number of mol = 232 grams/ 32.065 g/ mol

= 7.235 mol

7.235 mol of S are in the given sample

The ph of a 0.55 m aqueous solution of hypobromous acid, hbro, at 25.0°c is 4.48. what is the value of ka for hbro?
elena-14-01-66 [18.8K]

The solution would be like this for this specific problem:

Given:

 

pH of a 0.55 M hypobromous acid (HBrO) at 25.0 °C =  4.48

 

[H+] = 10^-4.48 = 3.31 x 10^-5 M = [BrO-] <span>

Ka = (3.31 x 10^-5)^2 / 0.55 = 2 x 10^-9</span>

 

To add, Hypobromous Acid does not require acid adjustment, which is necessary for chlorine-based product and is stable and effective in pH ranges of 5-9.<span>

</span>Hypobromous Acid combines with organic compounds to form a bromamine. Chlorine also combines with the same organic compounds to form a chloramine. <span>It is also one of the least expensive intervention antimicrobial compounds available.</span>
