Answer : The mass of NaCl required are 14.61 grams
Explanation : Given,
Molar mass of NaCl = 58.44 g/mole
Volume of solution = 500.00 mL
Molarity of NaCl = 0.5 M = 0.5 mole/L
Molarity : It is defined as the number of moles of solute present in 1 liter of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the mass of NaCl required are 14.61 grams
B. criteria because it's a principal or standard by which something may be judged or decided <span />
Answer is: True.
Example for p<span>olyhydroxyl alcohol is glycerol.</span>
Glycerol (1,2,3-Propanetriol, glycerine<span> or glycerin) is a simple polyol (it has three hydroxyl group) compound with formula (OH-CH</span>₂-CH(OH)-CH₂OH or C₃H₈O₃).
The glycerine <span>backbone is found in
all lipids known as triglycerides. (ester derived from glycerol and three fatty acids).
Glycerol is soluble in water and it is hygroscopic.</span>
Answer: 20 I think
Explanation:
1 in each corner, 3 across from it. 3x4=12 plus one next to each is 20
Answer:
x=2.
Explanation:
Hello there!
In this case, since we have a mole ratio of moles of Cl to moles of Cu as 2.39, it is possible to write the following:
Thus, since the two possible copper chlorides are CuCl and CuCl₂, we can therefore infer that x=2 since it is close but not as close as it should to the whole number 2.
Best regards!
