An organic compound that has the empirical formula CHO has a molecular mass of 145 amu. Its molecular formula is?
Answers
To Mark---DrBob222
empirical formula mass = 12+1+16 = 29
145/29 = 5
molecular formula = (CHO)5 or C5H5O5 and molar mass is ?
145/29 = 5
molecular formula = (CHO)5 or C5H5O5 and molar mass is ?
Stefhanie help me pls
the molar mass of C5H5O5 is 145. right?
DrBob222
right.
(5*12)+*5*1)+(5*16) = 145
(5*12)+*5*1)+(5*16) = 145
