C6H15, C2H5 has a molar mass of 29g/mol. 87 divided by 29 is 3. Then multiply each element subscript by 3
Answer:
<h3>Yeah, <em><u>Benzene have isomers.</u></em></h3>
Answer:
These are the isotopes of same element. i.e. hydrogen.
Explanation:
Protium and deutrium are the isotopes of hydrogen.
Isotope:
Atoms of same elements can have different atomic mass but same atomic number . These atom of an elements are called isotopes.
Hydrogen consist of three stable isotopes protium, deutrium and tritium.
These three isotopes are represented as H¹₁ , H²₁ and H³₁ respectively.
Protium consist of one proton and one electron while deutrium consist of one proton , one neutron and one electron. The number of neutron and proton is called mass number while number of electron or proton is called atomic number. The number of proton and electron are always same.That's why protium and deutrium have same atomic number but different atomic mass because there is no neutron present in protium that's why its atomic mass is less than by one from deutrium.
first find the atomic weight of CH3 which would be
atomic weight: 12.011 (3×1.008) = 36.32 g/mol
then find the moles in the given mass
36.32 ÷ 45.7 = 0.794
I HOPE I'M NOT WRONG I HAVENT DONE CHEM IN SO LONG
Any substance changes to another substance that means the change of the physical property. Like water () has different state which changes as the temperature changes. It remain as liquid in the room temperature, in solid form at or below 0°C and vapor phase on or above 100°C. But in all the stage or phase of the substance the composition of the water i.e. remains. Thus the chemical property remains fixed when a substance change to other substance.
