Nr of moles of C= mass of C/ molar mass of C
Molar mass of C =12.o1 g= A
In this case, A has measure unit in grams.
But measure unit for A is Dalton or amu.
Is the measure unit for A Dalton, amu, or grams?
When I compute No of moles for carbon , I use A= 12.01 g, not
A=12.01 amu.
For exemple: for mass of C=24 g C
Molar mass for: CO= A for C +A for O=
12.01+16.00=28.01g
In this case A for C =12.01 g
What is the measure unit A, grams,Dalton, amu?
Homework Answers
No of moles of C = mass of C / molar mass of C
Units of moles = mole
Units of mass = grams
Now
molar mass of C = mass of C / No of moles of C
So
Units of molar mass = grams/ mole
This is also called atomic mass unit(amu) or Dalton (1 amu = Dalton)
Hence measure unit is amu or Dalton
