Answer:
Molar mass= 78.8gmol-1
Explanation:
P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K
Applying
PV= m/Mm×(R×T)
Substitute and Simplify
Mm= 78.8gmol-1
Answer:
Le Chatelier's principle, also called Chatelier's principle or "The Equilibrium Law", is a principle of chemistry used to predict the effect of a change in conditions on chemical equilibria.
hope it helps ,pls mark me as brainliest
The correct answer is option 3. The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the electronegativities of the atoms in a molecule of the compound. Electronegativities of the atom tell how the electrons are distributed in the molecule.
