Answer:
0.0305 moles of MgCO₃
Explanation:
In order to solve this problem, we first need to calculate the molecular weight of MgCO₃:
- MgCO₃ MW = Atomic mass Mg + Atomic mass C + (Atomic mass O)*3
- MgCO₃ MW = 24.3 + 12 + 16*3 = 84.3 g/mol
Finally we <u>divide the mass by the molecular weight</u>, to calculate the <em>number of moles</em>:
- 2.57 g MgCO₃ ÷ 84.3 g/mol = 0.0305 moles.
Chloropicrin is obtained by the reaction of nitric acid on chloroform.
Answer:
carbon monoxide (CO) or nitric oxide (NO),
Explanation:
It's (grams-of-Cl/total-grams)(100), so (35.45g/58.44g)(100) = 60.66% Cl. Hope this helps!
