Explanation:
Ionic Compounds Are Balanced
Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-
A sample of tennantite with mass of 2370 g contains 19.23 mol Cu.
You must make the following conversions:
Mass of tennantite → moles of tennantite → moles of Cu
<em>Step 1</em>. Calculate the <em>moles of tennantite</em> (Tn)
The <em>ideal </em>chemical formula of Tn is Cu_12As_4S_13.
Molar mass = (12×63.55 + 4×74.92 + 13×32.06) g/mol
= (762.60 + 299.68 + 416.78) g/mol = 1479.06 g/mol
Moles of Tn = 2370 g Tn × (1 mol Tn/1479.06 g Tn) = <em>1.60 24 mol Tn
</em>
<em>Step 2</em>. Calculate the <em>moles of Cu</em>
Moles of Cu = 1.6024 mol Tn × (12 mol Cu/1 mol Tn) = 19.23 mol Cu
