1.	Find the molecular mass of the following. (1) H3po4 (2)caco3 (3)cao (4) mgo (5) Al2o3 (6) c2h5oh (7) C6h12o6 (8) c6h6 (9) Fe2o3 (10) Caso4 (11) Feso4 (12) Znso4 solve with explanation please help me.....
Answer» it is so simple add the MASS of the elements then u will get the molecular mass Explanation:for EXAMPLE ::: 1. h3po4 - h=1.3 = 3. p=1.31 =31. o4=16.4 = 64. now add them 3+31+64 =98
