Abottle of antiseptic hydrogen peroxide (h2o2) is labeled 3.0% (v/v). how many ml h2o2 are in a 400.0 ml bottle of this solution?

use this formula: percent by volume: volume of solute/volume of solution×100%

What happens when the temperature of a solution increases?

What is the percentage composition of carbon in the compound ch4

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
