What will be the pressure of a sample of 48.0 grams of oxygen gas in a glass container of volume 5.2 L at 25 degrees Celsius?
Molar Mass O2: 32.00, Molar Mass CO2: 44.01, T= 21C+273= 294Kelvins V=5.00 L Grams of O2=20.0 so moles O2= 20.0g/32.00g=.625g/mol Grams of CO2=4.4 so moles CO2= 4.4g/ 44.01=.1 Total moles: .625+.1= .725 mols (this is n) Ideal Gas Law: PV=nRT....Rearrange and solve for pressure. P=nRT/V.....R is the constant which is equal to .08206L*atm*mol P=(.725)(.08206)(294K)/(5.00L) P= 3.5atm
How do you get the density when the volume is bigger than the mass?
Well, first of all, you can never say that a volume is larger or smaller than a mass.Volume and mass are different physical quantities, they have different physicaldimensions, described in different units, and can't be compared or converted.When you talk about comparing a volume to a mass, the only thing you can compareis the numbers, but you have to remember that neither of them is just a number.In order to become a volume or a mass, the number needs to have a unit too.A 'density' is a mass divided by a volume. If the mass number is bigger than thevolume number, then the density number is more than ' 1 ' . If the mass numberis less than the volume number, then the density number is less than ' 1 '.But it doesn't mean anything. The same substance can give you a density morethan 1 or less than 1. It just depends on the units you use for mass or for volume.Let's say I have a lump of stuff in my hand. OK ? It doesn't matter what substance it is.Its mass is 50 grams, and its volume is 80 cubic centimeters. What's the density ?-- The density is 0.625 grams/cubic centimeter-- The density is 0.000625 kilogram/cubic centimeter-- The density is 625 grams/liter-- The density is 625 kilograms/cubic meter-- The density is 625,000 grams/cubic meterDensity can be a tiny number, a gigantic number, or in between. It just depends onthe units you use. The actual density doesn't change, and the object doesn't knowthat anything is happening, because the mass doesn't change, and the volume doesn'tchange. You're just changing the units of measure.
What is the difference between inconel 825 and inconel 625?
Inconel 200
What pressure is exerted by 625 mole of a gas in a 45.4 L container at -24 C?
The equation to use is the Ideal Gas Law: PV = nRT Rearranging for the unknown in your question (P) gives: P = nRT/V n = Number of moles: 625 R = Gas constant: 0.0821 L·ATM·mol-1·K-1 T = Temperature in Kelvin = 249 (Which is temperature in Celsius +273). V = Volume 45.4L So P = (625 x 0.0821 x 249) / 45.4 = 281.4 Atmospheres.
What is the pH of 535 ml of gaseous HCL at 26.5 degree C and 747 mmHg is dissolved in enough water to prepare 625ml solution?
Let's try this. PV = nRT ( 26.5 C = 299.65 K )(535 ml = 0.535 Liters ) (747 mmHg)(0.535 Liters) = (n)(62.36 L*torr/mol*K)(299.65 K ) = 0.021387 moles HCl(g) now.... Molarity = moles solute/Liters of solution (625 ml = 0.625 Liters Molarity HCl(g) = 0.021387 moles/0.625 Liters = 3.422 X 10^-2 M -log(3.422 X 10^-2 M) = 1.4657 pH final answer ( trim to significant figures )
How many grams are in 625 milligrams?
62.5 milligrams is 0.0625 grams.
How may grams is in 625 mg?
1 milligram (mg) = .001 grams (g) = 1/1000 grams Therefore, 625 mg * 1/1000 grams = .625 g which is less than 1 gram (g).
How many oz is 625 g?
625 grams is 22.05 ounces.
How many grams are in 625 mg?
0.625 Gram = 625 milligram
How many grams of alcohol would occupy 2.5mL?
If you think to ethanol the mass is 1, 973 625 g at 20 0C.
How many pounds in 3125 grams?
There are 1000 grams in one kilogram. Therefore, 625 grams is equal to 625/1000 = 0.625, or five eighths, of a kilogram.
625 mg ascorbic acid vitamin c equals how many grams?
In the metric system, the prefix "m" means 10-3 and "g" means grams. Therefore, 625 mg of anything = 0.625 grams.
How many grams in 025 ounces?
If u mean 25 ounces, there should be 625 grams.
A 0.25kg object displaces 625 ml of water round to nearest hundredth what is its specific gravity?
Specific gravity is the ratio of the mass of some volume of substance to the mass of same volume of water. Here 0.25 kg ie 2500 g is the mass of some volume of given substance. The volume of water displaced is 625 mL ie 625 cc. 1 cc of water has a mass 1g. So 625 mL has 625 g. Hence the specific gravity is 2500/625 = 4 (no unit)
What is 12.5 percent of 5 kilograms?
5 kilograms = 5,000 grams 12.5 % of 5,000 = 625 grams.
What is the molarity of a nitrous acid solution prepared by adding 245 mL of water to 625 mL of 5.7M nitrous acid?
625 ml of nitrous acid contains 3,5625 moles (0,625*5,7) The total volume increases from 625 to 870 (625+245) 3,5625/0,87=4,09 M
