For the complete combustion of 1.000 mole of methane gas at 298 K and 1 atm pressure, ΔH° = -890.4 kJ/mol. What will be the amou
nt of heat released when 1.97 g of methane is combusted under these conditions?

Answer:
0.70 M
Explanation:
- Molarity is the concentration of a given solution in moles per liter.
- Molarity is given in moles per liter of solution.
- It is calculated by dividing the moles of solute by the volume of solution.
In this case;
We are given;
Number of moles of HCl = 3.5 Moles
Volume of solvent, H₂O is 5.0 L
But,
Therefore;
= 0.70 M
Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter
