54 liters at STP (standard temperature and pressure)
10 moles of oxygen atoms or 5 moles of oxygen molecules.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
To find this answer you multiple Avogadro's number, 6.02x10^23, by the number of moles, 5.8, to get 3.4916x 10^24.
http://en.wikipedia.org/wiki/Chlorine 1 mol of chlorine (Cl2) weighs (2*35.45 =)70,90 grams 134,5 grams of chlorine is (134,5/70,9 =) 1,897 mol of chlorinegas. 1,897 * 6,02 * 10^23 = 1,142 * 10^24 molecules of Cl2
If the density of carbon tetrachloride is 1.59 g/L, the volume in L of 4.21 kg of carbon tetrachloride is about 2,647.8 L
To determine the number of atoms of chlorine in 445g of lead chloride (PbCl2), you need to calculate the number of moles of PbCl2 in 445g and then multiply it by the number of chlorine atoms in one PbCl2 molecule. First, calculate the number of moles of PbCl2 using the formula: moles = mass / molar mass. The molar mass of PbCl2 is 278.1 g/mol, so moles = 445g / 278.1 g/mol = 1.6 moles. Since there are two chlorine atoms in one molecule of PbCl2, the total number of chlorine atoms is 2 * 1.6 moles = 3.2 moles of chlorine atoms. To convert moles to atoms, multiply by Avogadro's number. Therefore, there are 3.2 moles * 6.022 x 10^23 atoms/mole = 1.9264 x 10^24 atoms of chlorine in 445g of PbCl2.
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
0.91/24 = 0.0379 moles of Mg produce 0.0379 moles of H2, and Volume of H2 at S.T.P is 0.0379 x 22.414 = 0.8498 dm3
At STP, water is a liquid with a density of 1000.000 grams per liter. The gram molecular mass of water is 18.01528. Therefore, the number of moles of water in one liter is 1000.000/18.01528 or 55.5084 moles. The number of molecules in one liter is therefore 55.5084 X 6.022 X 1023 or about 3.34272 X 1025, and the volume of one molecule is therefore 1 [exact]/3.34272 X 1025 or 2.99158 X 10-24 liter.
10 moles of oxygen atoms or 5 moles of oxygen molecules.
The answer is 3,587 moles.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
You need to apply the equation pV = nRT p = Pressure (1x10^5 Pa at STP) n = Number of moles (1.51x10^24 / 6.02x10^24) T = Temperature (273 K at STP) R = Universal gas constant (8.31) This gives the volume as 0.005 m^3
1 mol Cr/6.02x10^23 atoms x 3.6x10^24 atoms = 5.98 moles
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
Mass = Moles x Ar = 12.5 x 24 = 300g
4,515.10e24 atoms of magnesium is equal to 7,5 moles.
