24.8% HCl w/w means
24.8 g HCl/(100 g solution)
100 g solution = 24.8g HCl + 75.2g H2O.
mols HCl = grams/molar mass = ?
mols H2O = grams/molar mass = ?
total mols = ?
XHCl = mols HCl/total mols.
24.8 g HCl/(100 g solution)
100 g solution = 24.8g HCl + 75.2g H2O.
mols HCl = grams/molar mass = ?
mols H2O = grams/molar mass = ?
total mols = ?
XHCl = mols HCl/total mols.
