Asolution is 0.0460 m nabr. what is the molarity of the solution if the density is 1.10 g/ml?

The molarity of NaBr = 0.05036M

0.0460 m  NaBr    has 0.0460 moles NaBr with 1000g of solvent

therefore the mass of NaBr= 0.0460 moles x 102.89 g/mol =4.73grams

total mass is therefore= 4.733 g +1000= 1004.73 grams

step 2:

use the density to determine the volume

vol=mass/density

=1004.73 g/1.10 g/mol=913.39 ml in liters= 913.39/1000=0.91339 L

now the molarity = moles/vol in liters

=0.0460 m/0.91339=0.05036  M

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
