dovecameron to the most beautiful man I have ever known, and my best friend: yesterday marks 5 years since you've left us, and I still feel you all around me every day, all the time. I feel as though I understand you more and more as I begin to understand myself in these formative years, and although it can't ever replace the years I've lost with you, I know I am never without you because you are in me :) I am so happy every day, dad, and so is Claire. Both of your girls are following their bliss and living their great adventure. Taking no prisoners, loving all they can and eating ice cream bars and overly salted popcorn in bed. I wish you could meet all of the amazing people I've brought into my life and know how safe and loved I am. I know that wherever you are you know all of this, and you laugh at me when I speak as though you're gone. You taught me how to love, and you are love to me. The gift that you have given to me and Claire, the intense pain and loss, has brought a clarity, a deep human connection, an empathy and a color to our lives in a way that nothing else could. I can never go back to who I was before, and I would never want to. You still teach me lessons every day, and make me laugh as the lessons you instilled at a young age begin to settle into my bones and make more sense. You set me up for the best life imaginable, and I plan to make your proud every single day and never waste it. I love you eternally, and can't wait to see you again, maybe in our next life as we find each other over and over. Forever your best friend, and your little girl.

なぜ気体の状態方程式使うのか分かりません。ヘンリーのときの問題とも区別もつきません。この問題は状態方程式使うとか、分かるような区別の仕方ありますか。自分なりにはやってるんですけど、多分自分のやり方は間違えてて

K=39 アンモニ 比例する。 なる。 るため, 沸 透析 性溶媒 ■く見える す。 また、 する操作 O →問題 50 硝酸カ するので、 m=118.2 ol なので 8.3×103 基本例題8 気体の溶解度 0g=210g の差に相当 たがって, 22.4L/molが使える 問題 51.52 水素は、0℃ 0℃ LOK10Pa で、Lの水に 22mL溶ける。 次の各問いに答えよ。 DL の水に溶ける水素は何molか。 5 10℃, 5.0×10Pa で (20℃,5.0×105Paで1Lの水に溶ける水素の体積は、その圧力下で何mL か。 (3) 水素と酸素が1:3の物質量の比で混合された気体を11の水に接触させて 0℃, 1.0×10Pa に保ったとき、水素は何mol溶けるか。 H=1.0 C=12 N=140=16 (1) 0℃, 1.0×105Paにおけ る溶解度を物質量に換算する。 溶解度は圧力に比例する。 (2) 気体の状態方程式を用い 考え方 解答 ヘンリーの法則を用いる。 4 (1) 0℃, 1.0×105Paで溶ける水素の物質量は, 2.2×10-2L =9.82×10-4mol 22.4L/mol 気体の溶解度は圧力に比例するので, 5.0×105Pa では, 5.0×105 9.82×10mol× =4.91×10mol=4.9× 0-3mol る。 | 別解 溶解する気体の体 積は,そのときの圧力下では, 圧力が変わっても一定である。 (3) 混合気体の場合,気体の 溶解度は各気体の分圧に比例 する。 Jon れきたらへ DVENRTを使う 「考え方 (1) At=Km から凝固点降 下度を求める。 (2) グルコースの物質量を [n [mol], 溶液の体積をV [L], 絶対温度をT[K] と すると, ファントホッフの 法則 NLV=nRT が成り立 つ。 12.5×105.1L m2 とする 251.0×1071412+16+ (14+1+1)×2=60g/mol 出するか。 基本例題 9 希薄溶液の性質 次の各問いに答えよ。 ただし, 水のモル凝固点降下を 1.85K kg/mol とする。 (1) 2.4gの尿素 CO (NH2)2 を水100g に溶かした水溶液の凝固点は何℃か。 (2) 1.8gのグルコース C6H1206 を水に溶かして100mLにした水溶液の浸透圧は、 27℃で何Paか。 180) TT 1.0×105 (2) 気体の状態方程式 PV = nRT から V を求める。 4.91×10-3mol×8.3×10° Pa・L/ (K-mol)×273K 5.0×105 Pa =2.2×10-2L=22mL 別解 圧力が5倍になると, 溶ける気体の物質量も5 倍になる。 しかし, この圧力下で溶ける気体の体積は、 ボイ ルの法則から1/5になるので,結局, 同じ体積 22mLになる。 (3) 水素の分圧は1.0×10Pa ×1/4=2.5×10 Paなので, 溶ける水素の物質量は, 9.82×10-mol×(2.5×105/1.0×105) = 2.5×10-3 mol →問題 54~57 ■解答 (1) 尿素 (分子量60) は (2.4/60) mol, 溶媒の水は100g= 0.100kgなので, 凝固点降下度は, (2.4/60) mol △t=1.85K.kg/mol× -=0.74K 0.100 kg したがって, 凝固点は 0℃ -0.74℃ =-0.74℃となる。 (2) グルコース (分子量180) は (1.8/180) mol, 水溶液の体積 は 0.100Lなので, I = (n/V) RT から, (1.8/180) mol II = -x8.3x10³ Pa L/(K-mol) x (273+27) K=2.5×105 Pa 0.100L 第Ⅰ章 物質の状態
