Answer:
1.1 × 10⁻⁴ M
Explanation:
Let's consider the following double displacement reaction.
CuCl₂(aq) + 2 AgNO₃(aq) → 2 AgCl(s)+ Cu(NO₃)₂(aq)
We can establish the following relations:
- The molar mass of AgCl is 143.32 g/mol.
- The molar ratio of AgCl to CuCl₂ is 2:1
The moles of CuCl₂ that reacted to produce 7.7 mg of AgCl are:
The molarity of CuCl₂ is:
Answer:
<h2>Density = 0.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass = 60 g
volume = 120 mL
Substitute the values into the above formula and solve
That's
<h3>We have the final answer as
<h3>Density = 0.5 g/mL</h3>Hope this helps you
