Convert 25.00 g NaCN to moles. moles = grams/molar mass.
Using the coefficients in the balanced equation, convert moles NaCN to moles Au.
Now convert moles Au to grams. g = moles x molar mass.
Using the coefficients in the balanced equation, convert moles NaCN to moles Au.
Now convert moles Au to grams. g = moles x molar mass.
