Answer:
The molarity is 90 M
Explanation:
Molarity is a measure of concentration that indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml). In this case we calculate it that way:
200 ml solution ------18 mol CaCl2
1000ml solution----------x= (1000ml solutionx18 mol CaCl2)/200 ml solution
x=<em>90 mol CaCl2---> the solution is 90 M</em>

Answer: can u explain ur question please?
Explanation:
Answer:
The concentration of CH₃OH in equilibrium is [CH₃OH] = <em>2,8x10⁻¹ M</em>
Explanation:
For the equilibrium:
CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5
Thus:
14,5 =
In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:
14,5 =
Solving, the concentration of CH₃OH in equilibrium is:
<em>[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M</em>
I hope it helps!
