In areas where resistance is present, otherantimalarials<span>, such as </span>mefloquine<span> or atovaquone, may be used instead. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations.</span>
Answer:
3.05 g
Explanation:
The reaction that takes place is:
As the decomposition not necessarily was complete we'll work with the<em> given mass of product formed</em>. We convert <u>the 12 grams of chlorine to moles</u>, using its <em>molar mass</em>:
- 12 g ÷ 70.906 g/mol = 0.169 mol
Then we <u>convert Cl₂ moles to H₂O moles</u>:
- 0.169 mol Cl₂ *
= 0.169 mol H₂O
Finally we <u>convert moles to grams</u>:
- 0.169 mol H₂O * 18 g/mol = 3.05 g
Answer:
C
Explanation:
if we were to followw the IUPAC
1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution. Details about molarity can be found below.
<h3>How to calculate molarity?</h3>
The number of moles of a solution can be calculated by multiplying the molarity of the solution by its volume. That is;
no of moles = molarity × volume
According to this question, a solution has a molarity of 8.20M and volume of 125 mL of solution.
no of moles = 8.20 × 0.125
no of moles = 1.025moles
Therefore, 1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution.
