The volume of 1mole of hydrogen bromide at STP is 22.4 liters The gram-formula mass of hydrogen bromide is 80.9 grams per mole What is the density of hydrogen bromide at STP?
The molar volume of a gas at STP is 22.4 liters/mol. The molar mass of hydrogen bromide is 80.9 g/mol. Therefore, the density of hydrogen bromide at STP is 80.9 g/mol / 22.4 L/mol = 3.61 g/L.
How can 1mole of hydrogen gas occupy 22.4ltrs of volume when you know that a gas occupies all the space available to it?
At standard temperature and pressure. This means that, more or less, there are 6.022 X 10^23 diatomic molecules of H2 in that much volume. ( the volume not being under more than standard pressure; 760mm/Hg ) In twice the volume about twice the molecules under STP.
Is 1 liter equal to 1 mole?
No. A liter is a volume measurement for fluids (liquids and gases). A mole is 6.022 x 1023 of anything. In gases at STP, 22.4L = 1mole.
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
How many moles of ammonium bromide can be produced from 250 moles of bromine and 600 moles of ammonia?
Ther answer is none! ammonium bromide is made from hydrogen bromide and ammonia NH3 + HBr = NH4Br i mole of each makes 1mole of ammonium salt.
How much volume does 1 mole of a gas occupy at NTP?
PV=nRT. So at ntp P=1bar. If n= 1mole. R= .082. T=273K. Then 1V=1.273 .082. v=22.44 l of gas
How many particles are present in 1mole of a pure substance?
The number of Avogadro is 6,022 140 857(74).10e23.
How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
To find the number of moles of hydrogen sulfide, divide the given mass by the molar mass of hydrogen sulfide. The molar mass of hydrogen sulfide is approximately 34.08 g/mol. Thus, 64.6 g / 34.08 g/mol = 1.9 moles of hydrogen sulfide in the sample.
How many moles of gas does a steel cylinder witha volume of 45 liters contain at standard temp pressure?
stp= 22.4 dm3, 1L = 1 dm3 1mole ---> 22.4dm3 xmole ---> 45dm3 45/22.4 = 2.001 moles
What mass of hydrogen contains the same number of atoms as 7.00g of nitrogen?
Let's see. 7.00 grams nitrogen (1 mole N/14.01 grams)(6.022 X 10^23/1 mole N) = 3.01 X 10^23 atoms of nitrogen 3.01 X 10^23 ( 1mole H/6.022 X 10^23)(1.008 grams/1 mole H) = 0.504 grams of hydrogen
How do you calculate the number of atoms in a block of aluminum that is 2 cm x 4 cm x 1 cm?
Volume of block = 8cm3. The density of Al is 2.7 g/cm3 Density = mass/volume Mass=Density*Volume Mass= 21.6g 21.6g Al *(1mole/26.98g) = .8 moles Al .8moles*(6.022*1023atoms/mole) = 4.82*1023 atoms
What is the mass of 1mole of mgso4?
120.4
