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>
A hydrogen atom forms one bond, an oxygen atom forms two, and carbon forms four bonds.
Since the content of the closed is only hydrogen sulfide (H2S) it is then concluded that the initial pressure will still be equal to the pressure at the equilibrium state. Therefore, the answer to this item is 0.224 atm.
In ionic bonding, atoms SHARE ELECTRONS
