Answer:
the osmolarity of the 0.85% NaCl solution is approximately equal to 300 mosmol/L.
Explanation:
Molarity= number of moles/volume of the solution in liters
volume of the solution= 100 mL
1 L= 1000 mL
100 mL= 100/1000=0.1 L
molar mass of NaCl= 58.44 g/mol
number of moles= mass in gram/gram molecular mass
= 0.85/58.44
= 0.01455
molarity= number of moles/volume of the solution in liters
= 0.01455 / 0.1
= 0.1455 M
1 M= 1000 mM
so 0.1455 M = 0.1455 × 1000
= 145.5 mM
Osmolarity is the concentration of solutes in the solution.
NaCl dissociates to Na+ and Cl-
so osmolarity of 145.5 mM NaCl= 2 × 145.5
= 291 mosmol/L
Therefore, we conclude that the osmolarity of the 0.85% NaCl solution is approximately equal to 300 mosmol/L.
There had been new discoveries of chemicals that have been added to the periodic table in recent years
Mo₂O₆
Explanation:
The probable formula of its oxide is Mo₂O₆ in combined form.
The formula MoCl₆ gives us insight about the combining power of element Mo;
To form MoCl₆;
Mo Cl
Combining
power 6 1
Exchange 1 6
Compound MoCl₆
Now we know that the combining power of Mo is 6
Using the periodic table, we know that the combining power of oxygen is 2
Combining powers of an atom is the number of electrons is gains, shares or loses during a chemical combination:
Mo O
Combining
power 6 2
Exchange 2 6
Compound Mo₂O₆

Answer:
Depletion is the movement of the cost of natural resources from a company's balance sheet to its income statements. The objective is to match on the income statement the cost of the natural resources that were sold with the revenues of the natural resources that were sold.

There are three other structural isomers of 1-butanol: 2-butanol (sec-butyl alcohol), 2-methyl-1-propanol (isobutyl alcohol), and 2-methyl-2-propanol (tert-butyl alcohol). 2-Butanol, or sec-butanol, or sec-butyl alcohol, or s-butyl alcohol, is a four-carbon chain, with the OH group on the second carbon.
Chemicals of this type: Ethanol
