Hello student, hope you are safe and healthy!

After the woman completed her kidney transplant, the problem of rejection of the transplanted kidney arises. This is because her body will think this new kidney is “foreign” and will try to protect her by “attacking” it. To prevent this rejection, anti-rejection

a certain public water supply contains 0.10 ppb of chloroform .how many molecules of chloroform would be obtained in 0.478 ml drop of this water ?

Prabhav Sharma 26th Jul, 2020

Hi Garima,

It is given that there is 0.10 ppb of chloroform in a certain water supply, which means 10^9 g of water contains 0.10 g of CHCL3 ( because 1 billion = 10^-9)

Now volume of water = 0.478 mL (given)

Assume density of water to be 1 g/mL

hello adnan,

As we know that for a molecule, molecular weight in grams is equal to the Avogadro number and for transforming between moles and grams, we could use the molar mass of the substance. Avogadro’s number can be expressed as the number of elementary particles such as molecules, atoms,

If 2 molecules of sucrose have to be respired then the number of atp produced by anaerobic oxidation of glucose

Sohamsengupta8 21st Jul, 2020

Hello student,

As per we know that the respiration of 1 mole sucrose in UN aerobic oxidation produced 2 adenosine triphosphate.

So 2 molecules of sucrose are used in produced by anaerobic oxidation the total number of atp produced is about 4 nos.

And if  it is done by aerobic

Hello Gaikwadomkar,

As we know to find maximum number of molecules  we have to divide the given mass by its molar mass to get moles, then multiply times 6.022×1023 molecules1 mol

Now to answer your question 1 mole of any element contain 6.023 x 1023 number of molecules.

1 g

Hello sumittamrakar,

Hope you are doing well, Now coming back to the question as we know

An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. It is made from particles called protons, neutrons and electrons called the subatomic particles.

A box contains n molecules of gas. How will be the pressure of the gas be effected. If the number of molecules is made 2n

Sourav singh 28th Nov, 2021

Hello gaddamnagasaiteja,

As we know that pressure depends only on the force between them.

Now to answer the question, there will be no change in the pressure of the gas if we increase the no of molecule twice the previous . As pressure is independent of the  number of molecules
