Answer:
26 amu
Explanation:
atomic mass of C = 12 amu
atomic mass of H = 1.0008 amu
so, molar mass of C2H2
=(2×12 + 2×1.0008 ) amu
=(24 + 2.0016) amu
= 26.0016 amu

Answer:
Molar mass of ethyne, C₂H₂ = Mass of C × 2 + Mass of H × 2
= 12 × 2 + 1 × 2
= 24 + 2
= 26 g/mol
The molar mass of a substance is the mass of 1 mole of its molecules. the molar mass of a substance has 6.022 × 10²³ molecules of the substance in it.
