First, find the molar mass of C6H12O6 (180.156 g/mol)
Then, using avagadro's number (6.02*10^23), find the amount of molecules in the sample.
(2.3*10^-3g)/180.156 g/mol = 0.0000128 mol
(0.0000128 mol)(6.02*10^23)= 7.6856*10^18 molecules

and noble gas has there outermost shell electron filled up they complete there duplet or oclet valency state that why there inert in there natural state
Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
Answer:
779 g of chlorine would produce 7.3 moles of AlCl₃
Explanation:
Given data:
Mass of chlorine gas = 779 g
Number of moles of Aluminium chloride formed = ?
Solution:
Chemical equation:
2AlBr₃ + 3Cl₂ → 2AlCl₃ + 3Br₂
<em>Number of moles of chlorine:</em>
Number of moles = mass/ molar mass
Number of moles = 779 g/ 71 g/mol
Number of moles = 11 mol
Now we will compare the moles of chlorine with Aluminium chloride.
Cl₂ : AlCl₃
3 : 2
11 : 2/3×11 = 7.3 mol
779 g of chlorine would produce 7.3 moles of AlCl₃.
