0.1 mole of compound ‘S’ will weigh ___________ g.

(Given molar mass in g mol⁻¹ C : 12, H : 1, O : 16)

The sum of sigma (σ) and pi (π) bonds in Hex-1,3-dien-5-yne is ________.

Let $ L_1: \frac{x-1}{1} = \frac{y-2}{-1} = \frac{z-1}{2} $ and $ L_2: \frac{x+1}{-1} = \frac{y-2}{2} = \frac{z}{1} $ be two lines. Let $ L_3 $ be a line passing through the point $(\alpha, \beta, \gamma)$ and be perpendicular to both $ L_1 $ and $ L_2 $. If $ L_3 $ intersects $ L_1 $, then $ 5 \alpha = 11 \beta - 8 \gamma $ equals :
