Beryllium (Be) is a silver-white and very light metal with very high melting point at 2349 F (1287 °C). The combination of its light weight and high melting point makes it valuable for making metal alloys which are used in electronic and electrical components, aerospace, automobiles, computers, oil and gas drilling equipment, and telecommunications. The most common mineral containing beryllium is beryl, Be3Al2Si6018. Beryl is a cyclic silicate formed by linking six tetrahedral SiO4 units cyclically. In an ore of beryllium, beryl is associated with other minerals such as garnet, mica, and feldspar. In one mined ore, it contains 12% andradite garnet, Ca3Fe2(SiO4)3, 6% zinnwaldite mica, KLiFeAl2Si3010(OH)2F, 8% labradorite feldspar, CaNaAl(SiO4)2, and the rest is beryl. Calculate the following if the ore contains 2.5 tonnes of beryl. (Atomic masses: Ca=40, Fe=55.85, O=16, Si=28.09, K-39, Li-6.94, Al-27, F=19, Na=23, Be=9.01) g-mol mica b. kg-atom Be c. kg 02 d. SiO4 molecules e. Al atoms
