a gas mixture consists of 320 mg of methane , 175 mg of ar and 225 mg of neon. The partial pressure of neon at 300 k is 8.87 kPa. Calculate the volume and the total pressure of the mixture
For a material to float on the surface of water, the material must have a density less than that of water (1.0 g/mL) and must not react with the water or dissolve in it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g.
In a 0.400 mol/kg aqueous solution of sucrose, the molarity of sucrose is 0.282 mol/dm3 and the density of water is 0.998 g/cm3 at 20oC and 1 atm. Estimate the osmotic pressure of this solution.
Problem- Warfarin (C19H16O4, 308.34 g/mol) converted to CHI3. One mole of CHI3 was produced for each mole of warfarin that reacted. The collected CHI3 was reacted with silver to precipitate the iodine as AgI according to the following reaction.
Explain what will be the partial pressure of di-t-butyl peroxide after 1.00 hr if its initial partial pressure was 169.0 torr? Explain what will be the total gas pressure after 1.00 hr
A Breathalyzer instrument contains two ampules, each of which contains 0.75 mg K2Cr2O7 dissolved in 3 mL of 9 mol L?1 H2SO4(aq). One of the ampules is used as reference. When a person exhales into the tube of the Breathalyzer, the breath is direct..
Compute the pH at the temperature of 25 0C of a solution prepared by mixing 50 mL of 1.60 M sodium hydroxide solution to 0.5 of .0850 M Furoic acid HC 5 H 3 O 3 .
A beaker containing 250 mL of a 0.500 M solution of acetic acid COOH) is added to 125 mL of a 0.850 M solution of sodium carbonate. The reaction that ensues produces carbon dioxide, sodium acetate COONa), and water. How many grams of carbon dioxid..
The density of niobium is 8.58g/cm3. It's atomic mass is 92.91 g/mol and its structure is bcc. (a) Calculate the lattice parameter and the atomic radius from this information. (b) What is the planar density of atoms in the (110) plane (and sketch ..
