STP is 760. i hope this helps
Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
<em>Moles O = Moles S:</em>
12.5g O * (1mol / 16g) = 0.781 moles
<em>Mass S:</em>
0.781 moles * (32g / mol) =
<h3>25.0g is the mass of sulfur</h3>
To calculate the hydronium ion concentration for a solution that has a pH of 10.61, you would do the following. Since pH=-log[H3O+]. Input the pH value and solve for [H3O+].
10.61=-log[H3O+]
-10.61=log[H3O+]
-10.61=log10[H3O+]
[H3O+]=10^-10.61
[H3O+]= 2.4547x10^-8.
