Answer:
824 g
Explanation:
First we <u>convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles</u>, using <em>Avogadro's number</em>:
- 7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂
There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl
Finally we <u>convert 23.24 moles of chlorine into grams</u>, using <em>chlorine's molar mass</em>:
- 23.24 mol * 35.45 g/mol = 824 g
I believe the correct answer among the choices listed above is option D. Rusting is caused by the chemical weathering that leads to the breakdown of rocks. This chemical weathering is caused by oxidation or the reaction with oxygen.
