I'll be using dimensional analysis to help out.
2.5mol Na2O * ( X gNa2O / 1 molNa2O) = ? gNa2O
X gNa2O is the molar mass of the molecule. To find that we must add up the molar masses of all of the elements in the molecule.
There are 2 Na (Sodium).
And 1 O (Oxygen).
The Molar Mass of Na = 2 * 22.99 g/mol (It's multiplied by 2 because there are 2 of them in the molecule)
The Molar mass of O = 16.00 g/mol
If you are confused on where I found them. Let me enlighten you! I found them from a periodic table of elements.
Add those two values together to get a total molecular molar mass of:
38.99g/mol
2.5mol Na2O * ( 38.99 gNa2O / 1 molNa2O) = 97 gNa2O
Answer:
A metabolic pathway
Explanation:
Biologically, a metabolic pathway is a series of chemical reactions in which the end product of a reaction serves as a substrate (or reagent) for the reaction thereafter, the reactions being interdependent with one another. These reactions are catalyzed by enzymes. The metabolic pathways are fundamental for the maintenance of the cell and consequently of the body's homeostasis.
An example of the metabolic pathway can be seen in the above question where glucose is converted to glucose 6-phosphate by hexokinase. Glucose 6-phosphate then serves as a substrate for the enzyme phosphoglucose isomerase, which converts this reagent to fructose 6-phosphate. Fructose 6-phosphate serves as a substrate for phosphofructokinase, which converts fructose 6-phosphate into fructose 1,6-bisphosphate.
Answer : The formal charge on central Cl atom is -1.
Explanation :
The given molecule is,
First we have to determine the total number of valence electrons in,
As we know, chlorine has 7 valence electrons.
Total number of valence electrons in = 3(7) + 1 = 22 electrons
Electrons used in bonding pair = 4
Electrons used as lone pair = 22 - 4 = 18
Now we have to calculate the formal charge on central Cl atom.
- Formal charge = Number of valence electrons of a central atom - (2 × Number of lone pairs) - Number of bond pairs
Formal charge on central Cl atom = 7 - (2 × 3) -2 = -1
Therefore, the formal charge on central Cl atom is -1.

The molality of the lithium ions is calculated as 0.906 m
<h3>What is the molality of lithium ions?</h3>
Given that the compound is written as Li₃PO₄, the dissociation of the compound is given by the equation;
Li₃PO₄ -----> 3Li^+ + PO₄^3-
Since there are three mole of lithium ions in the compound, it the follows that the molality of the lithium ions is;
3 * 0.302 m = 0.906 m
