Okay so i have a lab report due and we had about 5 questions to answer and i did them but i just want to make sure they are correct. In the experiment we reacted tin with nitric acid to produce SnO2 . I measured 1.35 g of tin and 1.47 g of oxygen. So you will need to know that for the questions, thanks and Merry Christmas!!
1. Determine the percentage composition of the tin-oxygen product.
2. Analysis of 20.30 g sample of a compound containing phosphorus and oxygen showed that 8.87 g of sample were phosphorous. Calculate the empirical formula of the compound.
3.Upon analysis a compound was found to contain 7.75% hydrogen and 92.25% carbon by mass. Calculate the empirical formula for this compound.
4. By other experiments, the molecular mass of the compound in Problem 3 was found to be 78. What is the molecular formula?
5. Write the correct formula for the substance having a mass of 322 g and composed of 63.73% Na2S2O3 and 36.27% water.
