What is the percentage by mass of solution formed by dissolving 27.0 grams of hcl in 102.0 grams of water? 26.5% 20.9% 18.2% 16.7%

The answer is 20.9%; you have to divide the solute by the total number of grams; thus divide 27/129 and get B)20.9%

20.9%;

Explanation:

Did the test and it is right

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

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".
