the density of a gas is 1.25 grams/liter. which of the following is correct to convert the density of the gas to ounce/milliliter? [1 gram = 0.04 ounce, 1 liter = 1,000 milliliter]

multiply 1.25 by 0.04 and divide the result obtained by 1,000
divide 1.25 by 0.04 and multiply the result obtained by 1,000
divide 1.25 by the product of 0.04 and 1,000
multiply the numbers 1.25, 0.04, and 1,000

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
