This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): ch3co2h an analytical chemist has determined by measurements that there are 1.204 moles of carbon in a sample of acetic acid. how many moles of hydrogen are in the sample? round your answer to 4 significant digits.

2.408 moles of hydrogen are in the sample.

Explanation:

Molecular formula of acetic acid =

Ratio of carbon to hydrogen :

Measured  number of moles of carbon atoms = 1.204

Let the moles of hydrogen be = x

Number of carbon atoms in 1.204 mol =

Number of hydrogen atoms in x mol =

As we know that ratio of carbon to hydrogen atoms is 1:2.

x = 2.408 moles

2.408 moles of hydrogen are in the sample.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

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