In the present study, we have used the opposite approach, keeping the number of embryos constant and changing the media volume, and have found that optimum embryo density is dependent on oxygen concentration. The reasons for the interaction between embryo density and oxygen are unclear.

For example, the density of gasoline is about 30% less than that of water, and the density of chloroform is about 50% greater. Densities vary with temperature. For example, the density of water at 4°C is 1.000 g/mL and at 80°C is 0.9718 g/mL; the density of oxygen is 1.43 g/L at 0°C and 1.10 g/L at 80°C.
Density is mass per unit volume. Finding the density of a gas is the same as finding the density of a solid or liquid. You have to know the mass and the volume of the gas. The tricky part with gases is that you are often given pressures and temperatures with no mention of volume.
EXERCISE 2-1 Density. 5 26% by mass aqueous sodium chloride is added to a graduate cylinder (mass of cylinder = 85.550 g) to the 35.0 mL mark. The cylinder and contents now weigh 127.445 g.
Jan 13, 2009· Best Answer: 010101, The drop of volume 0.070 mL, has a density of 1.149 g/mL; the mass of O2 is 0.070 mL x 1.149 g/mL = 0.08043 grams. The moles of O2 = 0.08043 grams/(32.0 g/mole) = 0.002513 moles. From the Ideal Gas Law, PV = nRT, so V = nRT/P. Therefore,
Example #7: Dry ice is solid CO 2, with density of 1.56 g/mL. A small block of dry ice, measuring 1.25 cm x 1.90 cm x 2.80 cm, is sealed inside a balloon and allowed to sublime at room temperature, 22.0 degrees C, and 749 torr.
RP-1 (alternately, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel.RP-1 has a lower specific impulse than liquid hydrogen (LH 2), but is cheaper, stable at room temperature, far less of an explosion hazard, and far denser.RP-1 is significantly more powerful than LH 2 by volume.
The SI unit of density is the kilogram per cubic meter (kg/m 3), but in chemistry density is given in g/L or g/ml. Since 1 liter equals 1000 cm 3, 1 ml = 1 cm 3, and g/ml equals g/cm or g/cc. Grams per liter is used for gases, grams per milliliter is used for liquids and solids. Density is temperature dependent, since all substances change .
At a resting pulse rate, the heart consumes approximately 8-15 ml O2/min/100 g tissue. This is significantly more than that consumed by the brain (approximately 3 ml O2/min/100 g tissue) and can increase to more than 70 ml O2/min/100 g myocardial tissue during vigorous exercise.

Oxygen is the third most abundant chemical element in the universe, after hydrogen and helium. About 0.9% of the Sun's mass is oxygen. Oxygen constitutes 49.2% of the Earth's crust by mass as part of oxide compounds such as silicon dioxide and is the most abundant element by mass in the Earth's crust.
Sep 14, 2017· One mole of a gas at STP has a volume 22.4 L. So if we have the molar mass of the gas, just divide it by 22.4 to get the density of that gas. molar mass of O2 gas = 32 g/mol. Density = mass/volume =( 32g/mol) / (22.4 L/mol) = 1.428 g/l

Densities are higher, 0.82 to 0.85 g/ml, compared to RP-1 at 0.81 g/ml. For a short period, the Soviets achieved even higher densities by super-chilling the kerosene in a rocket's fuel tanks, but this partially defeated the purpose of using kerosene over other super-chilled fuels.
