The number of atoms in a mole of any pure substance is called?

Is it true that Avogadro did experiments to determine Avogadro's number?

echo "Enter A Number :"

read n

r=n

s=0

rem=0

while [ $n -gt 0 ]

do

rem=$(($n%10))

s=$(($s+$rem*$rem*$rem))

n=$(($n/10))

done

if [ $r -eq $s ]

then

echo "The Number is Avogadro"

else

echo "The Number is Not Avogadro"

fi

cho "Enter A Number :" read n r=n s=0 rem=0 while [ $n -gt 0 ] do rem=$(($n%10)) s=$(($s+$rem*$rem*$rem)) n=$(($n/10)) done if [ $r -eq $s ] then echo "The Number is Avogadro" else echo "The Number is Not Avogadro" fi

1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number
