Explanation:
Given parameters:
Mass of AgNO₃ = 1000mg
Volume of water = 500mL
Unknown:
Molarity of solution = ?
Solution:
The molarity of a solution is the number of moles of a solute dissolved in volume of solvent.
Molarity = 
Number of moles of AgNO₃ = ?
Number of moles = 
Molar mass of AgNO₃ = 108 + 14 + 3(16) = 170g/mol
convert mass to g;
1000mg = 1g
Number of moles =
= 0.00588moles
convert the given volume to dm³;
1000mL = 1dm³;
500mL = 0.5dm³
Now solve;
Molarity =
= 0.012moldm⁻³

The production of
is
. Converting mass into kg,
1 ton=907.185 kg, thus,

Thus, production of
will be
.
The specific volume of
is
.
Volume of
produced per day can be calculated as:

Putting the values,

Thus, volume of
produced per year will be:

Thus, in 4 year volume of
produced will be:

Answer:
The substance is a mixture because it left a white powder in the beaker when boiled.

The molar mass of CuCl2 is 134.45 g/mol; therefore, you divide 2.5 g of CuCl2 by 134.45 g of CuCl2 leaving you with 0.019 moles.
I hope this works.
