You are harvesting sio2, silicon dioxide in order to extract the silicon to use in computer chips. your employer wants to know how much silicon can be obtained from a 500g scoopful of quartz rock, which is pure silicon dioxide. calculate the number of grams of silicon is in the 500g of quartz rock.

Hello there!

If we assume that the quartz rock is pure silicon dioxide, we only need to use a conversion factor to go from grams of quartz rock (SiO₂) to grams of Silicon. The conversion factor uses the molar mass of SiO₂ (60,08 g/mol) and the atomic mass of Silicon (28,0855 g/mol):



So, 233,73 grams of Silicon can be obtained.

Have a nice day!

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
