What is the mass of 0.38 moles of cobalt (Co)?

The required mass is 22.04 g

Explanation:

We know,

Atomic mass of Co= 58g.

Now,

1 mole Co = 58 g

∴ 0.38 mole Co= (58 X 0.38) g

                         = 22.04 g

So, the required mass is 22.04 g

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
