An atom is basic unit of all the matter.

Matter can be an element, which has only single kind of atom in it. It is pure form of matter. For example gold is an element and has single kind of atom with same atomic numbers.

Matter can be a compound, which has two or more kinds of atoms.

Example water.

Neutron, proton and electron are sub atomic particles. Electrons are present around a central unit of atom known as nucleus.

Nucleus contains protons and neutrons both.

This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): an analytical chemist has det
zhannawk [14.2K]
<h3>Answer:</h3>

                    3.2 moles of Oxygen

<h3>Explanation:</h3>

                        Acetic Acid having chemical formula C₂H₄O₂ and structural formula attached below is the second member of carboxylic family in organic compounds. It is commonly used as vinegar<em> i.e</em>. a mixture containing 5 % Acetic acid and 95 % water.

As shown in structure 1 mole of Acetic acid contains 2 moles of Carbon atoms, 4 moles of Hydrogen atoms and 2 moles of Oxygen atoms respectively. Hence, the number of moles of Oxygen atoms contained by acetic acid containing 3.2 moles of Carbon is calculated as,

                      2 moles of C accompany  =  2 moles of O

So,

               3.2 moles of C will accompany  =  X moles of O

Solving for X,

                     X  =  (3.2 mol C × 2 mol O) ÷ 2 mol C

                      X =  3.2 mol of Oxygen

How many molecules are there in 4.00 l of oxygen gas at 500.∘ c and 50.0 torr?
Oliga [24]
From  the  ideal  gas law   
pv=nRT , n  is  therefore PV/RT
R is  the
R is  gas  constant =62.364 torr/mol/k
P=500torr
 V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the  number  of  molecules=moles  x avorgadro costant that is  6.022x10^23)
6.022 x 10^23)  x0.041=2.469 x10^22molecules
