ITEM 2: c) If 2.6g of X occupy a volume of 1.12dm³ at S.T.P. Determine its molecular formula. Step 1: Calculate the molar mass (M_r) of X. At S.T.P. (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 dm^3. We can find the molar mass using the given mass and volume: M_r = massvolume × molar volume at S.T.P. M_r = 2.6 g1.
