2 moles of gas exert a pressure of 2 atm. If some gas is pumped in, and only a total of 6 moles of gas results, what is the new pressure? Temperature and volume are constant.

What is the solubility of substance?

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
