Question

A metal chloride contains  of chlorine by weight.  vapours of the metal chloride at STP weigh . The molecular formula of the metal chloride is

Canvas Classes · Accepted Answer

Strategy:
 First, calculate the molar mass of the metal chloride using its vapour weight and volume at STP (). Then, find the number of Chlorine atoms per molecule by taking  of the molar mass and dividing by the atomic mass of Chlorine ().

Step 1: Calculate Molar Mass
 weighs  at STP.

Step 2: Find Chlorine count
Mass of Chlorine in 1 mole .
Number of atoms .

Step 3: Conclusion
The formula is .
