Question

i need help! please show it to me the steps to get the correct answer!Thanks!

Practice - Molar Mass Acetone or propanone, CH 0, is the main ingredient in nail polish remover and is used in industrial synthesis and as a solvent. The mass of one mol of acetone is a)29.0 g b)29.018 g c)30.026 g d)58 g e)58.080 g f)66.057 g 1.00794) 12011 15.9994

Answer 1

Molar mass of Hydrogen(H) = 1.00794 g/mol

Molar mass of Carbon(C) = 12.011 g/mol

Molar mass of Oxygen(O) = 15.9994 g/mol

Molar mass of Barium(Ba) = 137.38 g/mol

Molar mass of Phosphorous(P) = 30.97 g/mol

The mass of One mole acetone (C₃H₆O) is -

$\dpi{120} \bg_white (3\times 12.011+6\times 1.00794+15.9994) g/mol$

$\dpi{120} \bg_white = 58.080 g/mol$ (Option e)

The molar mass of Barium Phosphite Ba₃(PO₃)₂ is -

$\dpi{120} \bg_white 3\times 137.38 \: g/mol + (1\times 30.97+3\times 15.9994)\times 2 \: g/mol$

$\dpi{120} = 569.93\: g/mol$ (Option e)
