১১ মোল সালফিউরিক এসিডের আণবিক ভর কত?
To solve this problem, let's analyze it step-by-step:

Step-1: Here, we know that the chemical formula of Sulfuric acid is H2SO4

Step-2: The atomic mass of H (Hydrogen) is 1, atomic mass of S (Sulfur) is 32.07 ≈ 32 (rounding) and the atomic mass of O (Oxygen) is 16.

Step-3: So, total mass for 1 mole of H2SO4 is (1*2 + 32 + 16*4) = 98

Step-4: We have to find the mass for 11 moles of  H2SO4. So, mass for 11 moles is 11*98 = 1078         

#Answer: 1078
