Avogadros number is the definition of a mole. SO a mole is 1 avogadros number of atoms. molar mass is how much 1 avogadros number of atoms weighs. each element on the periodic table has a different mass, so 1 mole of each of the elements has a different molar mass.
The number of <span>neutrons that are present in its nucleus is 18. The correct option among all the options that are given in the question is the second option or option "B". Mass number minus the atomic number gives the number of neutrons. I hope that this is the answer that has come to your help.</span>
It was 40 I hope it helps
Answer:
a.v=u+v/2
a.v=s/t
combining two equation we get,
u+v/2=s/t
(u+v)t/2=s
(u+v)t/2=s
{u+(u+at)}t/2=s
(u+u+at)t/2=s
(2u+at)t/2=s
2ut+at^2/2=s
2ut/2+at^2/2=s
UT +1/2at^2=s
proved
a=v-u/t
at=v-u
u+at=v
No I do not agree. It is because work is done when force acting o a body displace or covers certain displacement in the direction of force applied .
