It is beacuse the ions in the melted or aqueous ionic compound is mobile and can freely move through the fluid and conduct electricity.
Answer:
0.0250 g
Explanation:
Step 1: Determine the molar mass of Vitamin C.
The molar mass is the mass in grams corresponding to 1 mole. In order to calculate the molar mass of vitamin C (C₆H₈O₆) we need to add the molar masses of the elements that compose it.
M(C₆H₈O₆) = 6 × M(C) + 8 × M(H) + 6 × M(O)
M(C₆H₈O₆) = 6 × 12.01 g/mol + 8 × 1.01 g/mol + 6 × 16.00 g/mol
M(C₆H₈O₆) = 176.14 g/mol
Step 2: Calculate the mass corresponding to 0.000142 mol of vitamin C.

Answer:
The answer is (D).
Explanation:
A(n) "electromagnet" is an electric circuit that produces a magnetic field.
<span>Mg(ClO2)2 has an atom of magnesium, 2 moles of chlorine and 4 moles of oxygen. </span><span>Al(ClO2)3, on the other hand, is composed of one mole of aluminum, one mole of chlorine and six moles of oxygen. The number of molecules of both is equal to 6.022 x10^23 molecules per mole of the compound.</span>
