Answer:

276g of K₂CO₃

Explanation:

Calculate the weight of K₂CO₃ in 2 moles:

K = 39g, C = 12g, O = 16g

         1 mole K₂CO₃ = (39 × 2) + 12 + (16 × 3)

                                 = 78 + 12 + 48

                                 = 138g

    ∴ 2 moles K₂CO₃ = 138 × 2

                                 = 276g

         ∴ There is 276g of K₂CO₃ in 2dm³ of the solution

(I'm sorry if this is not what you were asking for...I tried my best to work with the information given.)

                                                                          Hope this helps! :)

Answer:

Hey mates

Here is your answer

276g of K₂CO₃

Explanation:

Calculate the weight of K₂CO₃ in 2 moles:

K = 39g, C = 12g, O = 16g

         1 mole K₂CO₃ = (39 × 2) + 12 + (16 × 3)

                                 = 78 + 12 + 48

                                 = 138g

    ∴ 2 moles K₂CO₃ = 138 × 2

                                 = 276g

         ∴ There is 276g of K₂CO₃ in 2dm³ of the solution
