To find the grams of NH3 needed to provide the same number of molecules as in 0.693 g of SF, we need to use the molar ratios from the balanced chemical equation N2 + 3H2 -> 2NH3.
To find the grams of NH3 needed to provide the same number of molecules as in 0.693 g of SF, we can use the molar ratios from the balanced chemical equation:
N2(g) + 3H2(g) -> 2NH3(g)
From the equation, we can see that 2 moles of NH3 are produced for every 3 moles of H2. We can use the molar mass of NH3 to convert moles to grams.
First, we need to calculate the number of moles of SF in 0.693 g. Then, we can use the molar ratio to find the number of moles of NH3. Finally, we can convert the moles of NH3 to grams using the molar mass.
