Correct Answer Logic:

From the reaction: M$_2$CO$_3 + 2\text{HCl} \to 2\text{MCl} + \text{H}_2\text{O} + \text{CO}_2$

1 mol M$_2$CO$_3$ produces 1 mol CO$_2$.

Moles of M$_2$CO$_3 =$ moles of CO$_2 = 0.01186\ \text{mol}$

Molar mass $= \dfrac{1\ \text{g}}{0.01186\ \text{mol}} \approx \mathbf{84.3\ \text{g mol}^{-1}}$

Agronomy QUESTION #2075
Question 3173
Weeds are classified as 'obligate weeds' when they:
  • Can survive equally well in cultivated and natural undisturbed habitats
  • Are exclusively associated with cultivated land and cannot persist in natural plant communities — their survival depends entirely on the disturbance created by agricultural operations✔️
  • Are resistant to all registered herbicides in a given crop
  • Produce allelopathic chemicals that suppress crop germination
Correct Answer Logic:
Obligate (or agrestal) weeds are ecologically specialized to agricultural habitats — they germinate with crop seeds, mimic crop morphology (Vavilovian mimicry), and cannot compete in undisturbed natural vegetation. Examples include Phalaris minor in wheat and Echinochloa crus-galli in rice. Their persistence is entirely dependent on continued soil disturbance through tillage.
