What is the concentration of a solution formed by mixing 89.94 grams of cobalt (II)

sulfate in enough water to make 68.6 cL solution?

I keep getting .84 M. Can anyone explain how to get the right answer?

Explanation:

Hello,

In this case, cobalt (II) molar mass is 280.996 g/mol since it is about heptahydrate, so we compute the moles:

Then, since we need the volume in litres only:

Finally, we compute the molarity:

So your answer should be refined.

Best regards.

girl imma just put my comment here because i need a couple point okurrttt

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
