The answer is B. A guitar generally produces sound waves that propagate when the strings are strummed. The strings are displaced through the vibrations caused by contact of the hand and the guitar. You will also notice the vibrations by looking closely to the string. Wave particles continuously collide with each other to make a sustaining or prolonging sound.
The correct question is as follows:
How do you convert from grams to moles of a substance
1. Divide by the molar mass
2. Subtract the molar mass
3. Add the molar mass
4. Multiple by the molar mass
Answer: In order to convert from grams to moles of a substance divide by the molar mass.
Explanation:
The number of moles of a substance is the mass of substance in grams divided by its molar mass.
The formula to calculate moles is as follows.
This means that grams are converted to moles when grams is divided by molar mass.
Thus, we can conclude that in order to convert from grams to moles of a substance divide by the molar mass.

Explanation:
To balance this equations first count how many times an element is on each side and then see what needs to be changed in order to balance them.
11 electrons , 11 protons , 12 neutrons.
Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
