What is the mass of 4.55 moles of CH2O? The density of CH2O is 1.31 g/mL. The molar mass of CH2O is 30.03 g/mol.
+37084 The molar mass is given as 30.03 gm / mol you have 4.55 moles just multiply them together
30.03 gm/mol x 4.55 mol = 136.64 gms in 4.55 moles CH2O
+37084 .....you didn't ask, but perhaps you are looking ofr the VOLUME of 4.55 moles of CH2O ?
You have the mass (my first post ) 136.64 gm and you have the density
134.64 gm / 1.31 gm/ml = 102.78 ml
