Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
Answer:
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
Explanation:
As we know
C1V1 = C2V2
C1 and C2 = concentration of solution 1 and 2 respectively
V1 and V2 = Volume of solution 1 and 2 respectively
Substituting the given values, we get -
mg/mL
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
Answer:
83%
