A hydrocarbon \( C_n H_m \) is burnt in air (O\(_2\) + 3.78N\(_2\)). The stoichiometric fuel to air mass ratio for this process is 
Note: Atomic Weight: C(12), H(1) Effective Molecular Weight: Air(28.8)

A cut slope is made in a silty clay soil for a new road project, as shown in the figure. The locations of the ground water table (GWT) and potential failure surface are shown in the figure. After the cut is made, the excess pore water pressure is fully dissipated, and the shear stress at the point A is 60 kN/m². The factor of safety at the point A for long-term stability is .......... (rounded off to 2 decimal places).
