Answer:
8.4 mol.
Explanation:
The pressure and temperature are constant. The only variables are the volume and number of moles, so we can use <em>Avogadro’s Law</em>:
The <em>volume of a gas is directly proportional to the number of moles</em>.
V = kn
or
V₂/V₁ = n₂/n₁ Multiply both sides by n₁ and transpose
n₂ = n₁ × V₂/V₁
n₁ = 2.00 mol; V₁ = 1.34 L
n₂ = ? mol; V₂ = 7.00 L Solve for V₂
n₂ = 2.00 × 7.00/1.34
n₂ = 2.00 × 5.223
n₂ = 10.4 mol
===============
The balloon originally held 2.00 mol of helium. It now holds 10.4 mol.
Moles added = 10.4 – 2.00
Moles added = 8.4 mol
There are two atoms of N.
Answer: Glucose (C6H12O6) is a hexose -- a monosaccharide containing six carbon atoms. Glucose is an aldehyde (contains a -CHO group). Five of the carbons plus an oxygen atom form a loop called a "pyranose ring", the most stable form for six-carbon aldoses.
