৬ মোল কার্বন ডাই অক্সাইড এর আণবিক ভর কত?
To solve this problem, let's analyze it step-by-step:

Step-1: Here, we know that the chemical formula of Carbon dioxide is CO2

Step-2: The atomic mass of C (Carbon) is 12, and the atomic mass of O (Oxygen) is 16.

Step-3: So, total mass for 1 mole of  CO2 is (12 + 16*2) = 44

Step-4: We have to find the mass for 6 moles of  CO2. So, mass for 6 moles is 6*44 = 264 

#Answer: 264
