Answer:
1.840 x 10⁻³ mol HBrO₃
Explanation:
To find the moles of bromic acid (HBrO₃), you should (1) convert milligrams to grams (by dividing by 1,000) and then (2) convert moles to grams (via molar mass from periodic table).
Molar Mass (HBrO₃): 1.008 g/mol + 79.904 g/mol + 3(15.998 g/mol)
Molar Mass (HBrO₃): 128.906 g/mol
2.372 x 10² mg HBrO₃ 1 g 1 mole
---------------------------------x----------------x------------------ = 1.840 x 10⁻³ mol HBrO₃
1,000 mg 128.906 g
CₓHₐ + (x+a/4)O₂ = xCO₂ + a/2H₂O
n(CO₂)=4.69 mg/44.01 mg/mmol = 0.1066 mmol
n(H₂O)=1.10 mg/18.02 mg/mmol = 0.06104 mmol
C : H = 0.1066 : 0.06104*2 = 0.1066 : 0.12208 = 1 : 1.1453 = 7 : 8
C₇H₈ + 9O₂ = 7CO₂ + 4H₂O
C₇H₈
Answer:
C. The less energy the organism requires, the more efficient the energy transfer.
