Chemistry: While performing a blatant flop togain a foul called on the opposing team, LeBron James scrapes his knee and begins to bleed. His personal doctor bursts ontothe court with hydrogen peroxide (H2O2) in to clean up his wound. If the doctor applied 6.43 x 1029 molecules of hydrogen peroxide to the infected area, how many grams of hydrogen peroxide (H2O2) were used? A)3.14 g H2O2B)1.317 x 1055g H2O2C)3.63 x 107 g H2O2D)1.138 x 1052g H2O

2.5 L.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n and T are constant, and have two different values of V and P:

P₁V₁ = P₂V₂

P₁ = 5.0 atm, V₁ = 3.5 L.

P₂ = 7.0 atm, V₂ = ??? L.

∴ V₂ = P₁V₁/P₂ = (5.0 atm)(3.5 L)/(7.0 atm) = 2.5 L.
