The pOH of a solution : 13.756
<h3>Further explanation</h3>
Mass HCl=10.4 g
mol HCl (MW=36.5 g/mol) :

Volume of HCl = 500 ml = 0.5 L

HCl ⇒ H⁺ + Cl⁻
[H⁺]=[HCl]=0.57 M
pH= - log[H⁺]
pH=-log[0.57]=0.244
pH+pOH=14
pOH=14-0.244
pOH=13.756
Avocados and tomatoes were mainly eaten by the Aztecs and Maya.
<h3>
How did Mayans cook their food?</h3>
"Mayans cooking method includes digging a shallow pit, lining it with stones or clay balls.

First convert the inches cubed to centimeters cubed. Looking at the rate, we can write 2 inches cubed = 2 * 16.39 cm cubed = 32.78 cm cubed.
The equation for density is D = M/V, where D is the density, M is the mass, and V is the volume. Substitute the values into the equation:
0.242 = M/32.78
Multiply by 32.78 on both sides.
The mass is about 7.93 grams.
Answer:
morlecular element is oxygen
PV=nRT<=> P=nRT/V=2,40*R*(273+97)/45 atm.
Calculate it. R is a number that is given, find it and use your math to solve.
