∙ 6y ago
To find the number of molecules in 0.95 grams of SF6, you would first calculate the number of moles of SF6 using its molar mass. Then, using Avogadro's number, you can determine the number of molecules. Next, you would convert this number of molecules to the number of moles of NH3 using the mole ratio between NH3 and SF6. Finally, you would convert the moles of NH3 to grams using the molar mass of NH3 to find the mass needed.

How many grams of NH3 are needed to provide the same number of molecules as in 0.55 grams of SF6?
molar mass NH3 = 17 g/molmolar mass SF6 = 146 g/molmolecules in 0.55g SF6 = 0.55g x 1mol/146g x 6.02x10^23 molecules/mole = 2.27x10^21 moleculesgrams 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?
To calculate the number of molecules in 21.6 grams of CH4, you need to first determine the molar mass of CH4 (methane). The molar mass of CH4 is approximately 16 g/mol. Next, divide the given mass (21.6 g) by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.

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.
