The low-temperature superfluid density, determined by transverse-field $\\mu$SR, suggests a fully-gapped superconducting state in Mo$_2$C, with a zero-temperature gap $\\Delta_0$ = 0.44 meV and a magnetic penetration depth $\\lambda_0$ = 291 nm. The time-reversal symmetry is preserved in the superconducting state, as confirmed by the absence of an additional muon-spin relaxation in the zero-field $\\mu$SR spectra.
