(3)なんですが、モル分率を出したいのに、なんで圧力が使えるんですか?また、ちなみにモル分率ってなんですか?

基本例題24 混合気体 図のように、3.OL の容器Aに2.0×10°Pa の窒素を,2.0Lの容器Bに1.0×10°Pa の水 妻を入れ、コックを開いて両気体を混合した。温度は常に一定に保っておいた。 混合後 問題213-214-215 の気体について,次の各問いに答えよ。 (1) 窒素の分圧は何 Paか。 (2) 全圧は何 Paか。 各気体のモル分率はそれぞれいくらか。 (4) 混合気体の平均分子量はいくらか。 題を A 積に 3.0L 2.0L コック 度を 考え方 解答 (1) 混合後の気体の体積は, 3.0L+2.0L=5.0Lである。 (2) ドルトンの分圧の法則から, P=P,+ PH。 (3)分圧=D全圧×モル分率から, 成分気体の分圧 混合気体の全圧 (4) 平均分子量Mは各成分気 体の分子量×モル分率の和で求 められる。N2の分子量は28, He の分子量は2.0である。 (1) ボイルの法則から,窒素の分圧 PN, は, 2.0×10Pa×3.0L PV PN2 =1.2×10°Pa 5.0L V2 L (2) 同様に,水素の分圧 PH。は, PVi_1.0×10 Pa×2.0L V。 Pre -=4.0×10*Pa 三 5.0L モル分率= したがって,全圧は, P=PN,+ PH,=1.2×10Pa+4.0×10*Pa=1.6×10Pa 4.0×10'Pa (3) No…2×10°Pa) Ne… 1,6×10 Pá -=0.25 1.6×10Pa 文g ,7 H2… 0.75 E(ししゃ「ないお M=28×0.75+2.0×0.25=21.5=22 (原子量) H=1.0 N=14 0=16
