tell me that when we find molar mass and when we find formula unit mass?
Give 1 example for both

And also tell their units

Best answer will be marked as brainliest

Good luck...

Molar mass
Common symbols
M
SI unit
kg/mol
Other units
g/mol

In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance.[1] The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.

snehal85: yeah!
TPS: you should add formula mass part

HERE I am trying to solv your problemby taking example+-------

Molar mass is the mass of a given molecule or compound but now the clinch here is that it remains neutral despite the presence of zillions of molecules. For ex: Molecular mass of CO2 =12*1 + 16*2=44.

2.But, now the formula mass is something different. IT IS THE MOLECULAR MASS OF THE WHOLE COMPOUND CONTAINING X NO. OF MOLECULES OF THAT COMPOUND. Let me clarify it with example: Like we have to find the formula mass of 10Na2SO4.H2O= 10[23*2+32+16*4+2*1+16*1] = 10*180= 1800.

So, it is pretty clear that formula mass is ‘x’ times the molecular mass of that compound.


snehal85: easy to find the molecular mass of a compound with these steps.
Determine the molecular formula of the molecule.
Use the periodic table to determine the atomic mass of each element in the molecule.
Multiply each element's atomic mass by the number of atoms of that element in the molecule.
TPS: this is wrong.
TPS: Formula mass is the mass of empirical formula.
TPS: Have you studied about empirical formula? empirical formula of C2H6 is CH3. empirical formula is tje simplest formula
sarveshkumar83: This is Not IN 9 so I didn't put him in confusion okkk
sarveshkumar83: Dear
snehal85: yeah plz
snehal85: i m in lX
sarveshkumar83: okkk
TPS: It's not a hard concept. for example, take hydrogen peroxide(H2O2). Its molecular mass is 34. its empirical formula is HO. So formula mass is 17.
