Question

Calculate the atomic mass of hexane​

Answer 1

Explanation:

$\\ \sf\longmapsto Atomic\:mass\:of\:hexane=C_6H_14$

$\\ \sf\longmapsto 6(12u)+14(1u)$

$\\ \sf\longmapsto 72u+14u$

$\\ \sf\longmapsto 86u$

Answer 2

Answer:

86.178 g/mol

Explanation:

Chemical formula of hexane is C6H14

Hexane, whose chemical formula is C6 H 14  has a molar mass of 86.178 g/mol

​  

 To find the molar mass of Hexane, we can look up the atomic masses from the Periodic table for each element that make up Hexane and multiply each by the number of atoms in the formula and then adds up everything.

Hexane has 6 Carbon atoms with one Carbon atom having an atomic mass of 12.011 g/mol

Hexane also has 14 Hydrogen atoms which each atom having a mass of 1.008 g/mol

∴ Molar Mass of Hexane =(6×12.011)+(14×1.008)=86.178
