Question

Assertion: 1 gram of salt in 1 kg of solution has a concentration of 1 ppm. Reason: ppm is defined as member of parts by mass of solute per million parts of solution. ​

Answer 1

Answer:

hey

Explanation:

1.89 ppm of lithium ions corresponds to 1.89 g of lithium in 1000000 g of solvent.

Thus, 1 kg or 1000 g of solvent will contain 1.89×10

−3

g of lithium.

This corresponds to

7

1.89×10

−3

=2.7×10

−4

mol of lithium.
