What does 16.0 grams of oxygen contains?
1 mole of O atoms, or 0.5 moles of o2 molecules.
How much magnesium sulphide can be made from 1.0gram of magnesium and 1.0gram of sulphur?
The formula of magnesium sulphide is MgS, showing that a formula unit has one atom of each element. The gram atomic mass of magnesium is 24.305 and that of sulphur is 32.06. Therefore, when magnesium and sulphur are present in equal amounts by mass, sulphur is the limiting reactant. 1.0/32.06 or 0.031 moles of sulphur atoms are present. Therefore, the maximum amount of MgS that can result from reaction is 0.031 formula units of MgS. The gram formula mass of MgS is 56.365, so that 0.031 formula units of MgS will have a mass of 1.7 grams, to the justified number of significant digits.
What has more atoms 2.88 grams of helium atoms or 16.4 grams of zinc atoms?
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
How many iron atoms present in 5.0 mol of iron metal?
Five iron atoms have a mass of 1.3155 x 10-22 grams.
What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
How many oxygen atoms are present in 1.659 grams of ozone gas?
1.659 [grams] / 47.998 [grams / mol] * 6.02214179(30)×1023 [molecules / mole] * 3 [atoms / molecule]. A bunch.
The mass of oxygen which contains the same number of atoms as those present in 64 grams of sulfur is?
The gram-atomic mass of sulphur is 32 and that of oxygen is 16, to two significant digits. Therefore, the mass of oxygen with the same number of atoms as 64 grams of sulphur can be found from the proportion m/64 = 16/32, or m = 32 grams.
How many molecules of bromine are present in 120 grams of bromine gas?
904,000,000,000,000,000,000,000 (9.04 X 10^23) Bromine atoms.
How many grams of iron are in 6.02 X 1023 atoms of iron?
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.
How many molecules are present in 691 grams of potassium carbonate?
30.115*10^23 molecules
How many number of atom in 32 gram of oxygen?
Oxygen in the form O2 has a molar mass of 31.9988 gmol-1. In one gram there will be 1/31.9988 mol = 0.0313 mol. One mole of O2 equals 6.022 x 1023 molecules of oxygen, and thereby 1.88 x 1022 molecules of O2 in 1 gram. Since O2 is diatomic there are twice as many atoms as there are molecules and the final calculation to determine the number if atoms is 1.88 x 1022 * 2 = 3.76 x 1022 atoms of oxygen.
How many atoms of nitrogen are in 1.2 grams of aspartame?
no of moles in aspartame =mass/molar mass=1.2/294=0.00408mols no of molecules=0.00408* avagadros no.=0.00408*6.022*10^23=0.02456*10^23 no. of atoms =no.of molecules*2(coz 2 atoms of nitrogen are present)=0.02456*10^23*2
How many atoms of aluminum are there in a sample of aluminum sulfide with a mass of 100 g?
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.
How many grams are in a sample of sulphur trioxide that has 1.88 x 1024 molecules?
1.88 X 1024 molecules SO3 (1 mole SO3/6.022 X 1023)(80.07 grams/1 mole SO3) = 250 grams sulfur trioxide ===================
How many molecules of aspartame are present in 4.50 of aspartame?
2.50 grams C14H18N2O5 (1 mole C14H18N2O5/294.304 grams)(18 moles H/1 mole C14H18N2O5)(6.022 X 1023/1 mole H) = 9.21 X 1022 atoms of aspartame
How many hydrogen atoms are present in 3.65 grams of water?
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
What does 16.0 grams of oxygen contains?
1 mole of O atoms, or 0.5 moles of o2 molecules.
