hi does anyone know how to answer these two questions... Induim has two peaks m/z-113 and m/z-115 and relative atomic mass of this sample is 114.5 calculate the ratio of the relative abundances of the two isotopes and the answer is 1:3 but I don't know how they got to the answer
and another completely different question is.. the relative formula mass is 138.2 of M2CO3 determine the relative atomic mass and deduce the identity of M and the answer is K and 39.1 but I don't know how they got to the answer please help me btw this is an aqa as chemistry questions thanks in advance
Also does anyone have access to the OCR F321 June 2014 mark scheme? I've got the paper but don't have the mark scheme and I've just realised they haven't been realised yet
How do you work out how many structural isomers an organic compound has? Do you just have to draw it in as many ways as you can? A question asked how many structural isomers does the alkane C5H12 have.
In the production of sulphuric acid sulphur dioxide is converted to sulphur trioxide byreaction with the oxygen in the air. What volume of air (assume 20% of the air is oxygen)would be needed to produce 150 cm3 of sulphur trioxide? Assume complete conversion ofsulphur dioxide to sulphur trioxide.
