Answer:
5.645 × 10⁻²³ g
Solution:
Step 1) Calculate Molar Mass of SH₂;
Atomic Mass of Sulfur = 32 g/mol
Atomic Mass of H₂ = 2 g/mol
--------------------
Molecular Mass of SH₂ = 34 g/mol
Step 2: Calculate mass of one molecule of SH₂ as;
As,
Moles = # of Molecules / 6.022 × 10²³
Also, Moles = Mass / M.Mass So,
Mass/M.mass = # of Molecules / 6.022 × 10²³
Solving for Mass,
Mass = # of Molecules × M.mass / 6.022 × 10²³
Putting values,
Mass = (1 Molecule × 34 g.mol⁻¹) ÷ 6.022 × 10²³
Mass = 5.645 × 10⁻²³ g
Answer:
A
Explanation:
The pit of a peach. Simply, because this is the only answer that actually claims the core of the Earth isn't a type of outer shell.
2h-7 I had that before unless I’m tripping but I did rechecked
The answer is D, pH greater than 7. This is because when you make a solution of potassium hydroxide, it leads to an excess of hydroxide ions in the water. Since the concentration of hydroxide ions is greater than that of protons, it causes the water to be basic. The basic range on the pH scale is always greater than 7.
