(58) the pressure of a gas in a tank is 422 psi at
20.0k. what is the pressure at 60.0k?
a. 1270 psi
7.480 atm
c. 1270 atm
d. 480 psi

1270 Psi

We are given;

We are required to determine the pressure at 60.0 K

Hence;

Therefore;

P₂=1266 Psi

   = 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

if you mean hydrogen and oxygen then water is the product
