Chemistry

A-CH3SH reacts with CO according to the following unbalancedchemical equation:

CH3SH + CO → CH3CO(SCH3) + H2S

Calculate the mass in grams of the excess reagent remainingafter the complete reaction of 2.17 g of CH3SH with 1.45 g of CO. ()

B- a compound containing only C, H and O was subjected tocombustion analysis. A sample of 4.270×101 g produced9.200×101 g of CO2 and 3.766×101 gof H2O. Determine the empirical formula of the compoundand enter the appropriate subscript after each element.

C( ) H( ) O( )

If the molar mass of the compoundis 204.266 g/mol, determine the molecular formula of the compoundand enter the appropriate subscript after eachelement.
C( ) H( ) O( )
