Answer:
See below.
Step-by-step explanation:
<em>Method 1:
</em>
You know that oxygen is a <em>non-metal.
</em>
If the compound is ionic, the oxygen must be combined with a <em>metal</em>.
The Mg must be a metal.
<em>Method 2:</em>
In the formulas of ionic compounds, the positive ion (usually a metal) is written first.
Assuming that you’re looking for the concentration of water in the solution, then it would be 0.028 M.
You would have to use the formula:
c1v1 = c2v2, where c =concentration and
v = volume
C1 = ?
V1 = 250 mL
C2 = 0.2 M
V2 = 35 mL
C1 x 250 mL = 0.2 M x 35 mL
C1 = (0.2 M x 35 mL) / 250 mL
C1 = 0.028 M of water added to 35mL of 0.2M HCl
Therefore, there is 0.028 M of water added to 35mL of 0.2M HCl
