Explanation:
Nathan L. In science, we have a name for this, called Avogadro's number, and it describes the number of representative particles in one mole of a substance. The inverse mole unit tells us there are 6.022×1023 particles of something *per mole*.

Explanation:
my friend what is "m" in 400m here.
by the way one mole of NaOH=(23+16+1)g
=40g
IF YOU MEAN IN 400 GRAMS NaOH
FOR 40GRAM ------------------------ 1mole
FOR 400GRAM ------------------------ 10mole
IF YOU MEAN IN 400 MILLIGRAMS NaOH
1mg=1/1000g
400mg=0.4g
FOR 40GRAM ------------------------ 1mole
FOR 0.4GRAM ------------------------ 0.01mole
