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?
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 are there in 29.777 grams of hydrogen peroxide H2O2?
To find the number of molecules in 29.777 grams of hydrogen peroxide (H2O2), you first need to calculate the number of moles in 29.777 grams using the molar mass of H2O2. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
How many molecules are there in 200 grams of CCL4?
To find the number of molecules in 200 grams of CCl4, first calculate the number of moles using the molar mass of CCl4. The molar mass of CCl4 is approximately 153.82 g/mol. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in that number of moles.
How many grams are in 8.281023 molecules of N2l6?
To convert the number of molecules to grams, first calculate the molar mass of N2O6. The molar mass of N2O6 is 92.02 g/mol. Then use this value to convert the number of molecules to grams using the formula: ( \text{Grams} = \frac{\text{Number of molecules}}{6.022 \times 10^{23}} \times \text{Molar mass} ) Calculate: ( Grams = \frac{8.281023}{6.022 \times 10^{23}} \times 92.02 )
How many molecules are contained in 55 grams of sulfuric acid?
To calculate the number of molecules in 55 grams of sulfuric acid (H2SO4), you first need to determine the molar mass of sulfuric acid, which is 98.08 g/mol. Next, find the number of moles in 55 grams by dividing the mass by the molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.

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.

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.
