Ответ:
b.
Same because, mass doesn’t count liquid or solid
Ответ:
392 g
Explanation:
The given concentration tells us that in 100 g of solution, there would be 15.3 g of 2-ethyltoluene.
With that in mind we can calculate how many grams of solution would contain 60.0 g of 2-ethyltoluene:
Mass of solution * 15.3 / 100 = 60.0 g 2-ethyltolueneMass of solution = 392 g
