Methanethiol (CH4S) has a disagreeable odor and is often a component of bad breath. When methanethiol burned, the sulfur reacts with oxygen to form SO2. What mass of SO2 forms upon the complete combustion of 1.89 of methanethiol?
Here, we are going to calculate the mass SO2 upon the complete combustion of 1.89 of methanethiol
Step 1 : The reaction is
CH3-S-H + O2 -----------> SO2(g) +CH4(g)
Molar mass of Methanethiol (CH4S) = 48.0489 g/mol
Molar mass of SO2 = 64.06 g/mol
Amount of Methanethiol (CH4S) = Mass/molar mass = 1.89 g/48.0489 g/mol
= 0.0393 mol of Methanethiol
Thus, from reaction,
1.0 mol of Methanethiol produces...
