Explanation:
The name of the compound tells you:
1 carbon atom + two sulfur atoms = CS2.
“di” == 2, e.g., carbon dioxide = CO2.
Many compounds tell you exactly what’s in them:
Sulfur dioxide: SO2
Sulfur trioxide: SO3
Carbon monoxide: CO
Carbon tetrachloride: CCl4
Other compounds have common names, mostly for historical reasons:
water: dihydrogen monoxide = H2O
methane: carbon tetrahydride = CH4
ammonia: nitrogen trihydrie = NH3
Suggestion: Use your favorite search engine to find the formula for almost any compound.
