Use the mole ratio and molar mass to covert to mass of HCI
To convert from moles of HCl to mass of HCl, you need to use the mole ratio and molar mass.
The mole ratio between HCl and HCl is 1:1, as per the balanced equation: 2HCl → 2H + Cl2.
You can use the molar mass of HCl, which is approximately 36.46 g/mol, to convert from moles to grams.
So, if you have the number of moles of HCl, you can multiply it by the molar mass of HCl to obtain the mass of HCl.
Mass (g) = Moles × Molar Mass
For example, if you have 0.5 moles of HCl, the calculation would be:
Mass (g) = 0.5 moles × 36.46 g/mol
= 18.23 g
Therefore, with 0.5 moles of HCl, the mass of HCl would be approximately 18.23 grams.
