Answer:
0.0107 mol
Explanation:
Multiply concentration by volume (in liters) to get moles.
0.5 M • 0.0213 L = 0.0107 mol
Answer:
50 mg.
Explanation:
From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,
<em> </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>
<em> 240 mL solution 20ml solution</em>
⇒ 2.5 mL of tussin
5 ml tussin contains 100mg guafenesin,
So,
⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin
A galvanic cell is formed when two metals are immersed in solutions differing in concentration, when two different metals are immersed.
<h3><u>What is a </u><u>

cell</u><u> ?</u></h3>
- In order to provide a pathway for the flow of electrons along that wire, the galvanic cell makes use of the ability to split the flow of electrons during the oxidation and reduction processes.
- It forces a half-reaction and connects each to the other with a wire.
- A galvanic cell is an electrochemical device that converts chemical redox reaction energy into electrical energy.
- Electrically, it has a potential of 1.1 V. Oxidation takes place at the anode, which is a negative plate in galvanic cells. It is a positive plate where the reduction happens.
- An electrochemical device called a galvanic cell transforms chemical energy's free energy into electrical energy. A photogalvanic cell produces species that are photochemically reactive.

<span>Paramagnetic, an easy way to check is to see if it is the last element within the orbital and you can do that simply by looking at the periodic table. The s orbital has two, the p has 6 so on and so forth. Some elements are considered diamagnetic if they are almost completely full. </span>
