A chemistry student needs 60.0 g of 2-ethyltoluene for an experiment. He has available 1.5 kg of a 15.3% w/w solution of 2 ethyltoluene in carbon tetrachloride Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button. Round your answer to 3 significant digits.

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:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
