Answer is: molar mass
of compound is 154,58 g/mol.<span>
m(</span>naphthalene<span>) = 10 g = 0,01 kg.
m(unknown compound) = 1,00 g.
</span>Δ<span>T (solution) = 4,47 °C.
Kf(</span>naphthalene) = 6,91°C/m<span>; cryoscopic
constant.
M</span>(unknown compound) = Kf(naphthalene)· m(unknown compound) ÷
m(naphthalene)<span> · ΔT(solution).
M(xylene) = </span>6,91°C/m<span> · 1 g ÷ 0,01 kg · 4,47</span>°C<span>.
M(xylene) = 154,58 g/mol.</span>
Answer: j.j. Thompson didn't know at the time of the nucleus so the belief that was missing from the plum pudding model would be the nucleus.
Explanation:
The answer is chloric acid. Hope this helps!
D. Phosphorus
You can tell what elements have how many valence electrons by what group they're in. Groups are vertical.
So group 1 has 1 valence electron
Group 2 has 2 valence electrons
Group 3 has 3 valence electrons, etc.
