If they didn't, they wouldn't be able to communicate their findings effectively. An international language is especially important for elements because many elements have similar properties (e.g. some of the transition metals).
Answer:
599.26 grams of potassium sulfate will be produced.
Explanation:

Moles of chromium (III) sulfate = 
According to reaction, 1 mole of chromium (III) sulfate gives 3 moles of potassium sulfate.
Then 1.1480 moles of chromium (III) sulfate will give:

Mass of 3.4440 moles of potassium sulfate:
= 3.4440 mol × 174 g/mol = 599.26 g
599.26 grams of potassium sulfate will be produced.
Answer:
