Depends on the molar mass.
1 oz = 28.34 grams1 gram = 0.03 oz
1 cup equals 200 grams
Use the following: 1.0 mole HCl = 36.46 g and 1.0 mole = 6.022*1023 molecules, to calculate: 1 molecule = 36.46(g/mol) / 6.022*1023(molecules/mol) = 6.054*10-23 gram
A simple way to do solve such problems is, first find the atomic mass of iron ie ferrous. Fe. If m is the atomic mass then change into gram. Then that amount is known as molar mass. Always a molar...
