The mass of 5.15 × 10²¹ atoms of chromium is 0.44 g
From Avogadro's hypothesis,
6.02×10²³ atoms = 1 mole of Cr
But:
1 mole of Cr = 52 g
Thus, we can say that:
6.02×10²³ atoms = 52 g of Cr
With the above information, we can obtain the mass of 5.15 × 10²¹ atoms of chromium. This can be obtained as follow:
6.02×10²³ atoms = 52 g of Cr
Therefore,
5.15×10²¹ atoms = (5.15×10²¹ × 52) / 6.02×10²³
5.15×10²¹ atoms = 0.44 g of Cr
Thus, the mass of 5.15 × 10²¹ atoms of chromium is 0.44 g

Tops stops spinning because it doesn't have energy or ran out of force for example when you spin a top you give force to it then after 30 sec it going to stop going slower and slower that Is losing energy that's how tops stops spinning
Answer:
no.
Explanation:
only one planet would be made gas
is earth. and for what you mean like when
planet would be made of gas my answer is no
because theirs so gravity but im not the one
who's deciding and god is the one who's deciding
if when is the other planet having a gas
i know im wrong
The answer is a. concentrated. (If the statement was instead that large amounts of water was involved and smaller amounts of salt, the answer would be instead c. dilute)
Answer:
Thallium < Lead < Carbon < Oxygen
Explanation:
The ionization energy of the elements are given as;
Lead - 710 kJ/mol
Carbon - 1090 kJ/mol
Thallium - 590 kJ/mol
Oxygen - 1310 kJ/mol
In increasing order, it is given as;
Thallium < Lead < Carbon < Oxygen
