How many grams of NH3 are needed to provide the same number of molecules as in 0.55 grams of SF6?

∙ 7y ago
molar mass NH3 = 17 g/mol
molar mass SF6 = 146 g/mol
molecules in 0.55g SF6 = 0.55g x 1mol/146g x 6.02x10^23 molecules/mole = 2.27x10^21 molecules
grams NH3 needed = 2.27x10^21 molecules x 1mol/6.02x10^23 molecules x 17g/mol = 0.064 grams

Calculate the number of molecules given grams i.e how many molecules are there in 21.6 grams of CH4?
You would multiply the number of grams x Avogadro's number=number of molecules: (21.6g) X (6.022x10^23)= 1.301x10^25 molecules
How many molecules are there in 200 grams of CCL4?
The gram molecular mass of carbon tetrachloride is 12.011 + 4(35.453) or 153.823. Each mole contains Avogadro's Number of molecules. Therefore, the number of molecules in 200 grams is (200/153.823) X Avogadro's Number or 7.83 X 1023 molecules, to the justified number of significant digits.

How can you convert from molecules to grams?
How many molecules are in 94 grams of sodium fluoride
How many molecules of carbon dioxide are there in 1.0 grams of the gas?
The gram molecular mass of carbon dioxide is about 44.01 grams. By definition, this value is the number of grams of carbon dioxide that contains Avogadro's Number ("AN") of molecules. Avogadro's Number is about 6.022 X 10^23. Therefore the number of molecules in 1 gram is (1/44.01)(AN) or 2 X 10^21 molecules, to the justified number of significant digits.
How many molecules are there in 200 grams of CCL4?
The gram molecular mass of carbon tetrachloride is 12.011 + 4(35.453) or 153.823. Each mole contains Avogadro's Number of molecules. Therefore, the number of molecules in 200 grams is (200/153.823) X Avogadro's Number or 7.83 X 1023 molecules, to the justified number of significant digits.
What is the number of molecules in 48.0 grams of oxygen gas O2?
9.03 × 1023
Why does 10 grams of nitrogen gas contains the same number of molecules as 10 grams of carbon dioxide?
The density of O2 is 31.9988 grams per mole, meaning there are 0.143 grams and 4.47 mmols present. The density of NH3 is 17.0305 grams per mole, giving 4.09 mmols of ammonia. This means that they have approximately the same number of mmoles, thus the same number of molecules.
