Answer:
Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1
Explanation:
because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
Answer:- 
.
Solution:- Aspartame is a artificial sweetener with molecular formula 
and it's molecular mass is 294.3 gram per mol.
We have been given with 4.50 mg of aspartame and asked to calculate the moles. For mass to moles conversion we divide the given mass in grams by molar mass.
Since, the mass is given in mg, we need to convert it to g first.
1 mg = 0.001 g
So, 
= 0.00450 g
Now let's calculate the moles on dividing the grams by molar mass as:
=
Hence, are present in 4.50 mg of aspartame.
well one thing that’s unique about water is the fact that it’s dipole, meaning that water has both a positive side and a negative side.
Answer:
As for your question, I know to forget to put the options, specifically that your question is incomplete.
Explanation:
Although it could help you by telling you that always a reaction that seeks to balance the pH, and achieve neutrality ... It is necessary to achieve a concentration of OH equal to that of H +, in this way the hydroxyl and the protons.
