The average density of planet earth is 5.52 g/cm3. Knowing that
Earth has a mass of 5.97*10^27g, determine the earth radius in
miles. ( 1 mile = 1609 meters).
What is the ratio of the mass of fresh water produced to the
mass of water in the incoming brine?Multi-stage flash distillation is used to
desalinate seawater so it is fit for human consumption. A flash
distillation tank is composed of small chambers (called
\"stages\"), each at a lower pressure than the previous stage. Salt
water enters the first chamber, some fresh water flash evaporates,
condenses, and is removed from the distillation tank. The remaining
salt water moves to the...
What mass of sucrose (C12H22O11) should be combined with 485 g
of water to make a solution with an osmotic pressure of 8.00 atm at
280 K ? (Assume the density of the solution to be equal to the
density of the solvent.)
What mass of sucrose (C12H22O11) should be combined with 461g of
water to make a solution with an osmotic pressure of 8.20atm at
305K ? (Assume the density of the solution to be equal to the
density of the solvent.)
Liquid 1: Water (density: 1g/cm3)
Water displaced = 156 mL
mass of object was found to be 156 g
Liquid 2: Saltwater (density: 1.02 g/cm3)
water displaced: 158.4 mL
Mass of object was found to be 161.568 g
Use what you know about Archimedes’ Principle: specifically the
equations and , where the wsubscript refers to
the liquid the object floats on and the o subscript refers
to the object itself. Derive a formula that relates the densities
of the object and...
What mass of sucrose (C12H22O11) should be combined with
4.60×102 g of water to make a solution with an osmotic
pressure of 9.00 bar at 310 K ? (Assume a density of 1.0 gmL−1 for
the solution.?
A 12.0 mass % solution of H3PO4 in water has a density of 1.104
g/mL. Calculate the pH in the solution.
Ka1= 7.1 × 10−3
Ka2 = 6.3 × 10−8
Ka2 = 4.2 × 10−13
1.Density water = 1 kg/m^3 and density of ice = 90% density of
water. How much of an ice cube in your glass of water is below the
surface? calculate the specific gravity of ice. (show work )
2. a piece of cork which weights 0.25 N in air and has a
specific gravity of 0.25 . If the cork is allowed to float in
water, what fraction of its volume will be above water ?
