In the determination of the molecular weight of chloroform vapour by Hofmann's method, the following results were obtained:
Weight of liquid in bulb = 0.2704 g; Volume of vapour = 110 cm³; Temperature of vapour
99.6 °C; Atmospheric pressure = 747 mmHg; Vapour pressure of water vapour at 99.6 °C =
285.2 mmHg. Calculate the relative molecular weight of chloroform if 1dm³ of H2 at S. T.P.
weighs 0.09 g. In your calculations, show your work clearly including manipulations of units.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

if you're asking what comes out, it's steam.
