C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and has molar mass of 132 amu.
This is impossible. In order to find this you must know the elements in the compound
HNO3
Element Element's atomic massC : 12H2 : 2(hydrogen's atomic mass is 1 but remember there are two)O : 16Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.12+2+16=30240/30=88(CH2O) = C8H16O8
From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
