I think it’s SO2 Im not quite sure but I think so
Answer : 1721.72 g/qt are in 18.2 g/cL
Explanation :
As we are given: 18.2 g/cL
Now we have to convert 18.2 g/cL to g/qt.
Conversions used are:
(1) 1 L = 100 cL
(2) 1 L = 1000 mL
(3) 1 qt = 946 qt
The conversion expression will be:
Therefore, 1721.72 g/qt are in 18.2 g/cL
Answer:
2.24 g
Explanation:
First we use the<em> PV=nRT</em> formula to <u>calculate the number of moles of the gas</u>:
- 0.957 atm * 1.30 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
Then we can use the<em> given molar mass</em> to <u>calculate the mass</u>:
- Molar Mass = Mass / number of moles
- 44.01 g/mol = Mass / 0.0509 mol

Answer:</h3>
1.380 × 10^-8 M

Explanation:</h3>
The pH is the measure of alkalinity or acidity of a substance.
It is the negative logarithm of H+ ions concentration [H+].
pH = -log[H+]
pOH on the other hand is negative logarith of OH- concentration [OH-].
pOH = -log[OH-]
In this case;
pOH = 7.86
We can calculate the [OH-]
pOH = -log[OH-]
But, pOH = 7.86
pOH = -log[OH-]
-log[OH-] = 7.86
[OH-] = Antilog -7.86
= 1.380 × 10^-8 M
Therefore, [OH-] is 1.380 × 10^-8 M
