In-oxide is a semiconductor useful in solar cells. X-ray diffraction data reveal that In-oxide has a cubic structure with 1 oxygen ion and 1 In ion effectively inside the cubic unit cell. Further, the length of the unit cell is estimated to be a 0.3133 nm. Calculate the density of In-oxide given the atomic weight of In 114.82 amu and the atomic weight of O 16.00 amu
In-oxide is...

I am supposed to find the individual and average weight percents of acetic acid in vinegar and the relative percent error between my average results and the manufacturers listed value. Data 6ml vinegar @ 5% acetic acid 3.585g vinegar 42.2ml of NaOH @ 0.100M I'm not sure how to do this at all and want to understand. I know we need to use the molarity equation somewhere. If anyone can list the steps I need to take to answer the...
Nitrous oxide (N20) is produced from ammonia nitrate under conditions such that 2000 kg of NH4NO3 produce 700 kg of N20. The equation for the reaction is: Atomic weight ofN is 14 g mol. O is 16 g mol. H is g mol-1 a) Calculate the percent conversion of NH4NO3 b) Calculate the percent yield on a mass basis. c) Calculate the percent yield on a mole basis. [2 marks] [1 mark] [1 mark]
