Achemistry student needs of isopropenylbenzene for an experiment. she has available of a w/w solution of isopropenylbenzene in carbon tetrachloride. calculate the mass of solution the student should use. if there's not enough solution, press the "no solution" button.

The question is incomplete, here is the complete question:

A chemistry student needs 10.00 g of isopropenylbenzene for an experiment. She has available 120. g of a 42.7 % w/w solution of isopropenylbenzene in carbon tetrachloride. Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button.

Round the answer to 3 significant digits.

The mass of solution that the student should use is 23.4 grams

Explanation:

We are given:

42.7 % (w/w) solution of isopropenylbenzene.

This means that 42.7 grams of isopropenylbenzene is present in 100 grams of solution.

To calculate the mass of solution when 10.00 g of isopropenylbenzene is needed, we apply unitary method:

For 42.7 grams of isopropenylbenzene, the amount of solution needed is 100 grams

So, for 10.00 grams of isopropenylbenzene, the amount of solution needed will be =

Hence, the mass of solution that the student should use is 23.4 grams

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
