F the solubility of a gas in water is 5.0g/L when the pressure of the gas above the water is 2.0 atm, what is the pressure of the gas above the water <span>when the solubility of the gas is 1.0 g/L</span>
Here's how to solve this one.
The formula for solubility is
<span>P1 / P2 = solubility1 / solubility2 </span>
P1=2*1/5= .4 atm
So the correct answer is 0.4 atm.
The correct answer would be 32/16s
B) A chemical change because the nail reacts with water/oxygen to create rust (a type of oxide)
Explanation:
36.5gm (Molar mass) = 1mole
1 gram = 1/36.5 mole
10grams =(1/36.5) x 10 moles
= 0.027 x 10 moles
=0.27moles
