Problem- How many moles of gas must be forced into a 3.5 L ball to give it a gauge pressure of 10.2 psi at 24oC? The gauge pressure is relative to atmospheric pressure so assume since atmospheric pressure is 14.7 psi the total pressure of the ball is 24.9 psi.
Determine the solution for the above problem express your work in detail
one reason carbon monoxide co is toxic is that it binds to theprotein hemoglobin more strongly than oxygen does. the
Describe how you would prepare the following aqueous solution: 230 g of a solution that is 0.60 molal Na2CO3 starting with the solid solute.
