Question

calculate the atomic mass of Pentene​

Answer 1

Explanation:

$\\ \sf\longmapsto Atomic\:mass\:of\:pentane=C_5H_{12}$

$\\ \sf\longmapsto 5(12u)+12(1u)$

$\\ \sf\longmapsto 60u+12u$

$\\ \sf\longmapsto 72u$

Answer 2

Chemical Formula of Pentene → C₅H₁₀

Atomic Mass of Pentene → (12*5) + (1*10)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀ → (60) + (10)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀ → 70 u
