Two hundred kg of liquid contains 40% pentane, and rest hexane. Pentane MW is 72.15 g/ gmol and SG (20C/4C) is 0.17. Hexane MW is 86.17 g/ gmol and SG (20C/4C) is 0.659. Determine a) the total number of moles, b) the mole fraction composition of the liquid, c) the average molecular weight and d) the average density of the solution.

A machine puts liquid into bottles of perfume. The amount of liquid put into each bottle, Dml, follows a normal distribution with mean 25ml. Given that 15% of bottles contain less than 24.63ml a.) find, to 2 decimal places, the value of k such that P(24.63<D<k) = 0.45 A random sample of 200 bottles is taken. b.) Using a normal approximation, find the probability that fewer than half of these bottles contain between 24.63ml and k ml The machine is...

You are given a substance that is equally soluble in water and hexane (two immiscible solvents). a.) If you start with 10 g of the substance dissolved in 100mL of water and are given 100mL of hexane to extract with how much will you extract into hexane if you do a single extraction with all 100mL of the hexane? b.) If you start with 10g of the substance dissolved in 100mL water and are given 100mL of hexane to extract...

There are 5 boxes. One box is empty; two boxes each contains one marble; and the remaining two boxes each contains two marbles. Suppose that the colors of the marbles are not known, but it is known that each marble can only be either red or green, with equal probability. Suppose that ONE box is randomly chosen from the 5 boxes, and let R denote the number of the red marble(s) the box has, and G be the number of...

Juice is put into bottles and sealed. Each bottle contains 1500 mL of product and has 65 mL headspace of air with 20% by volume of oxygen in it. The specific gravity of the product is 1.04. During packaging, the dissolved oxygen content of the product is 7.0 ppm. The juice concentrate contributes 5.5 mg Vitamin C per 100 mL to the final product mixture. The processor then adds an unknown amount of vitamin C to the product to bring...

Each of the following four sets contains two electrons, each of which is defined by four quantum numbers (n, l, ml, ms). For each set, indicate whether the quantum numbers for the two electrons are valid for the two electrons in the highest energy subshell of a neutral titanium atom. If they are not valid, list the principle that the quantum numbers violate (Pauli Exclusion, Aufbau, or Hund’s Rule) and explain below. (the numbers are shown below in the order...

Two liquid streams are flowing at constant rates into a blender. One is benzene, which flows at a measured rate of 20.0L/min, and the other is toluene. The blended mixture enters a storage tank (inner diameter = 5.5m) equipped with a sight gauge. During an interval in which no liquid leaves the storage tank, the liquid level in the tank is observed to increase by 0.15 meters over a one-hour period. Calculate the flow rate of toluene into the blender...
