What is the mass of 6.02x23 atoms of sulfur?
Avogadro's number is the number of units in one mole of any substance (defined as its molecular/atomic weight in grams), equal to 6.022140857 × 10 23. Using this we know that because the molecular weight of sulfur is 32.06, a mole of sulfur will weigh 32.06 grams.
How many grams are in half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
What is the mass in grams of one mole of sulfur dioxide SO2?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.S- 32.1O- 16.0SO- 48.1 grams in one mole
In order to get 1 mole of ammonia how many moles of nitrogen is needed?
Each mole of ammonia requires one mole of nitrogen atoms. However, the nitrogen in the air occurs as diatomic molecules; therefore, only one-half mole of molecular nitrogen is required for each mole of ammonia.
What is the mass of one mole of sodium atom?
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
What is the weight of one mole of sulfur?
The molecular weight of 1 mole of sulfur is 32 amu or grams.
Is the molecular weight and equivalent weight of aniline is same?
Yes, because its one mole reacts with one mole of HCl
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 do calculate how many mole are in grams?
For these conversions, you need the atomic masses of the elements involved in grams. If it is just one element, then you use the atomic mass, but if its a compound, then use the molecular mass (added atomic masses). Take the number of moles and multiply it by the atomic (molecular) mass to get number of grams.
How much mass does 0.50 mole of copper contain?
Weight of one mole of CuBr=molecular weight of CuBr=(63.545+79.904)=143.449 g. So, weight of 0.500 mole of CuBr=(143.449 X 0.500)g=71.725 g.
How many moles is in 5 grams of HCl?
To do this, you need to know the molecular weight of the element you're dealing with, by adding up the atomic weights of the elements involved (found on any periodic table). The molecular weight is the mass in grams of the compound in one mole - this will provide you with a conversion factor. So take the measurement in grams and divide it by the molecular weight to convert to moles. Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the molecular weight. That's the thought process behind unit analysis and how you get your "units to cancel". In this case, the answer is about 0.137 moles HCl.
How many Co atoms are there in 230 grams of CoCl2?
To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2
How do you get gram molecular weight?
gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g
What is the mass of 6.02x23 atoms of sulfur?
Avogadro's number is the number of units in one mole of any substance (defined as its molecular/atomic weight in grams), equal to 6.022140857 × 10 23. Using this we know that because the molecular weight of sulfur is 32.06, a mole of sulfur will weigh 32.06 grams.
What is the molecular weight of palm oil?
The average molecular weight of Palm oil varies from 810 to 855 grams per mole. Palm kernel oil is closer to 682 grams per mole (more stearic acid).
How many grams are in half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
How many grams in one mole?
That depends on the substance, and on whether you are considering atoms ore molecules. One mole has as many grams as the atomic or molecular mass of the substance. For example, one mole of atomic hydrogen has 1 gram; one mole of molecular hydrogen has 2 grams, one mole water has 18 grams, etc., since those numbers are the corresponding atomic or molecular masses.
