Assume all gan velumes are measured of the some temperature and pressure The combustion of propane is given by the equation: C_(3)H_(8(g))+5O_(2(g))=Longrightarrow 3CO_(2(g))+4H_(2)O_((g)) What volume of steam in cm^3 is formed by burning 20cm^3 of propane? [rgv-16] A. ? 80 B square 160 7 C. square 100 7 D. square 40 7

## Step1: Identify the stoichiometric relationship### From the balanced chemical equation, 1 volume of propane ( ) produces 4 volumes of steam ( ).## Step2: Calculate the volume of steam### Given 20 cm³ of propane, use the stoichiometric ratio to find the volume of steam: .
