When aluminum replaces up to half of the silicon atomsin SiO2, a mineral class called feldspars result. The feldspars are the most abundant rock-forming minerals, comprisingabout 50% of the minerals in Earth’s crust. Orthoclase is afeldspar in which Al replaces one-fourth of the Si atoms ofSiO2, and charge balance is completed by K+ ions. Determinethe chemical formula for orthoclase.
