Question

c₇h₁₆
express your answer in atomic mass units to two decimal places.
formula mass =
amu

Explanation:

Step1: Find atomic masses

Carbon (C) atomic mass: ~12.01 amu, Hydrogen (H) atomic mass: ~1.008 amu.

Step2: Calculate C contribution

7 C atoms: \( 7 \times 12.01 = 84.07 \) amu.

Step3: Calculate H contribution

16 H atoms: \( 16 \times 1.008 = 16.128 \) amu.

Step4: Sum contributions

Total formula mass: \( 84.07 + 16.128 = 100.198 \approx 100.20 \) amu.

Answer:

100.20
