Question

If a lab requires each a lab group (3 students) to have 25 ml of a solution and it takes 15 grams of AgNO₃ cuprous nitrate, to make 1 liter of solution, how many grams are needed to make enough solution?

Answer 1

Answer:

0.375 grams are needed to make 25 mL solution.

Explanation:

Mass of $AgNO_3$ cuprous nitrate required to make 1 l of solution = 15 g.

1 L = 1000 mL

Mass of $AgNO_3$ cuprous nitrate required to make 1000 mL of solution = 15 g

Mass of $AgNO_3$ cuprous nitrate required to make 1 mL of solution:

$=\frac{15}{1000} g$

Mass of $AgNO_3$ cuprous nitrate required to make 25 mL of solution:

$=\frac{15}{1000} \times 25 g=0.375 g$

0.375 grams are needed to make 25 mL solution.
