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>

This explanes all of what you need along with helpful videos an other things I found intersting for you HOPE IT HELPS YOU YOUR WELCOME.
The pressure of the gas is 246 kPa.
<em>p</em> = 2.43 atm × (101.325 kPa/1 atm) = 246 kPa
Don’t worry, you’re right :)
