Answer:</h3>
5.0 × 10^21 atoms of sulfur
<h3>
Explanation:</h3>
We need to know that 1 mole of an element contains atoms equivalent to the Avogadro's number.
Therefore;
1 mole of an element = 6.022 × 10^23 atoms
Thus, 1 mole of sulfur = 6.022 × 10^23 atoms
But, molar mass of sulfur = 32.065 g/mol
This means;
32.065 g contain 6.022 × 10^23 atoms
Therefore, 2.66 g of Sulfur will contain;
= (2.66 g ÷ 32.065 g/mol) × 6.022 × 10^23 atoms
= 5.0 × 10^21 atoms
Answer:
Mercury, Venus, and Mars are all smaller than Earth, and technically Pluto a well.

Explanation:
Answer:
2. Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
3. Since the vast majority of an atom's mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).
