Stainless steel is an alloy of iron, chromium, nickel, and carbon that does not rust. This allows it to be used without degradation for many years. Many people use "silverware" at home and restaurants that is produced from stainless steel rather than silver. The primary source of nickel that is used to produce stainless steel is mined from nickel (II) chloride, NiCl2. If a company mines 18 kg of NiCl2 a day, they are mining ____ moles of NiCl2 each day.
