Answer is: molar mass of sodium iodide is 149.89424 g/mol.
Chemical reaction: Na⁺ + I⁻ → NaI.
The molar mass (M)<span> is the </span>mass<span> of a given substance (in this example sodium iodide</span><span>) divided by the </span>amount of substance<span>.
</span>M(NaI) = Ar(Na) + Ar(I) · g/mol.
M(NaI) = 22.98977 + 126.90447 · g/mol.
M(NaI) = 149.89424 g/mol.
<span> Charge and it is surrounded by 5 electrons.</span>
Answer:
NiO Does Not Dissolve In An Aqueous Solution Of NaNO3.
Explanation:
Answer:
85.5%
Explanation:
To get the experimental value, you need to convert 15.0 grams of Na2SO4 to grams of Na3PO4. You do this with stoichiometry.
Convert grams of Na2SO4 to moles with molar mass. Then convert to moles of Na3PO4 with the mole-to-mole ratio according to the balanced chemical equation. Then convert moles of Na3PO4 to grams with the molar mass.
15.0 g Na2SO4 x (1 mol/142.04 g) x (2 Na3PO4/3Na2SO4) x (163.94 g/1 mol) = 11.7 g Na3PO4
Percent Yield = (actual value/experimental value) x 100
Actual Value = 10.0 g
Experimental Value = 11.7 g
10.0g/11.7 g = 85.5%
Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.
