Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
What is boiling point of 1 molar glucose solution?
A 1 molar solution by definition is 1 mole of something, in this case glucose, in 1 liter of solution. The molecular weight of something can be found on the perdiodic table. The weight listed on the periodic table is the grams in a mole, these of course are for atoms. 12 H + 6 C +6O + 188.1558 grams in a mole of glucose. Put this weight into one liter of water.
Which has the largest mass 10 mol of C or 3 mol of Cl or 1 mol of fructose?
Find the atomic or molecular weight of each and multiply it by the number of moles. atomic weight of carbon is 12 g/mole. atomic weight of chlorine is 35.45 g/mole molecular weight of fructose is 180.16 g/mole So just find the total grams. 10 moles Carbon * 12g/mole Carbon = 120 grams carbon 3 moles Chlorine * 35.45g/mole Chlorine = 106.35 grams Chlorine 1 mole Fructose * 180.16 g/mole Fructose = 180.16 grams Fructose So the answer is 1 mole of fructose.
How much does one mole of 0 weigh?
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
What is the molecular weight of H2?
The molecular weight of H2, which is a diatomic molecule of hydrogen, is approximately 2.01588 grams per mole.
What is the simplest formula for 0.080 mole Ba and 0.080 mole S and 0.320 mole O?
The simplest formula based on the given moles would be BaSO4 (barium sulfate). This is determined by dividing each mole value by the smallest mole value (0.080 mole), resulting in a ratio of 1 Ba : 1 S : 4 O, which corresponds to BaSO4.
When a .269 g sample of barium compound was treated with excess H2SO4 .0891 g of BaSO4 formed What is the percentage of barium in the compound?
The molar mass of BaSO4 is 233.4 g/mol. Therefore, 0.0891 g of BaSO4 corresponds to 0.000382 moles of BaSO4. Since BaSO4 contains 1 mole of Ba for every 1 mole of BaSO4, the original sample contained 0.000382 moles of Ba. The percentage of barium in the compound is calculated as (mass of Ba / total mass of the compound) * 100, which equals approximately 0.143%.
How many sulfur atoms are in 0.45 mol BaSO4?
There are 0.45 mol of BaSO4. In one mole of BaSO4, there is one sulfur atom. Therefore, there are 0.45 mol of sulfur atoms in 0.45 mol of BaSO4.
What is the weight of 1 mole of pure sodium?
The molar mass of sodium (Na) is approximately 22.99 grams per mole. Therefore, the weight of 1 mole of pure sodium is 22.99 grams.
What is the percentage of Ba compound when 0.269 g sample of Ba compound was treated with excess H2SO4 0.0891 g of BaSo4 was formed?
The molar mass of BaSO4 is 233.4 g/mol. From the given data, the number of moles of BaSO4 formed can be calculated as 0.0891 g / 233.4 g/mol = 3.82 x 10^-4 moles. Since 1 mole of BaSO4 contains 1 mole of Ba, the number of moles of Ba in the sample is also 3.82 x 10^-4. The percentage of Ba in the original sample is then (3.82 x 10^-4 moles / molar mass of Ba) x 100%.
What is the weight of one mole of sulfur?
The molecular weight of 1 mole of sulfur is 32 amu or grams.
What is the Weight of 1 mole in gram for oxygen?
16grams
What is carbon weight of one mole?
1 mole of carbon weighs 12,0107(8) g.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
How much does 1 mole of copper weigh?
The atomic weight of copper is approximately 63.55 grams per mole. Therefore, 1 mole of copper weighs around 63.55 grams.
What is the molecular weight of a compound in daltons and how does it convert to grams per mole (g/mol)?
The molecular weight of a compound is measured in daltons, which is a unit of mass used for atoms and molecules. To convert daltons to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.
What is the molecular weight of a compound in daltons and how can it be converted to grams per mole (g/mol)?
The molecular weight of a compound is the sum of the atomic weights of all the atoms in the molecule, measured in daltons. To convert this to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.
