問4の析出した水の計算で1/6/1/5をかけているのは何故ですか？濃度分をかけているというのは解説から読み取っ他のですがなぜそのように計算できるかが納得できていないです。教えて頂きたいです。よろしくお願いいたします。

8/20 2-1 固体の溶解度, 凝固点降下 日本医科大 C1=35.5 とする。 ただし, 塩化マグネシウムは水溶液中で完全に解離し, 文章中の溶液 A 次の文章を読み, 下記の問1~ 問4に答えよ。 原子量としてH=1.0,0=16.0, Mg=24.0, に対して希薄溶液の凝固点降下度を示す式が成立すると仮定する。 なお, 水100gに溶ける 塩化マグネシウム無水塩の最大の質量は 25.0℃で55.0g, 60.0℃で 61.0gであり、水のモ ル凝固点降下は 1.85 K kg/mol とする。 2 塩化マグネシウムは,水溶液中から沈殿させるとn水和物の結晶として析出する。 60.0g の塩化マグネシウム無水塩を 60.0℃ の蒸留水 100gに溶かし,この溶液を 25.0℃まで冷 却すると,MgCl2nH2Oの結晶が質量 x 〔g〕 だけ析出した。この結晶のうちの5.40gを 25.0℃ の蒸留水 50.0gに溶かし,これを溶液 Aとした。 溶液の凝固点降下度を測定した ところ 2.78 Kであった。 溶液の凝固点とは溶液が溶媒成分の固体と平衡状態にあるときの温度である。 凝固点降下 度とは純粋な溶媒の凝固点と溶液の凝固点との差であるから,溶液の凝固点と溶質濃度との 関係は凝固点降下度を示す式から導くことができる。 溶液 A を -3.33℃まで冷却し,この温度で溶液が氷と平衡状態にあれば,この溶液中の 塩化マグネシウム濃度は a 電離度のかけ忘れに 要注意 | mol/kgである。このとき塩化マグネシウムの結晶が生じ なるか, ていなければ氷の全質量は b gである。 問1 仮にn=2であればxはいくつになるか, 有効数字2桁で記せ。 問2 凝固点降下の実験結果から 25.0℃の溶液に含まれる塩化マグネシウムの質量モル 3 濃度 〔mol/kg] を求め, 有効数字2桁で記せ。 何を文字 スムーズか 考える!!! 問3 凝固点降下の実験結果からnとして最も適切な数値を求め, 整数で記せ。 問4 文章中の空欄 a と b に入る最も適切な数値を有効数字2桁で記せ。 囮の利用 の山

問4の⑤の計算はどうすれば合うのですか。 教えてください🙇‍♀️ 3枚目が答えです。

次の英文を読んで,下の設問に答えなさい。 Last year, 4.2 million babies died. That is the most recent number reported by UNICEF of deaths before the age of one, worldwide. We often see lonely and emotionally charged numbers like this in the news or in the materials of activist groups or organizations. They produce a reaction. Who can even imagine 4.2 million dead babies? It is so terrible, and even worse when we know that almost all died from easily preventable diseases. And how can anyone argue that 4.2 million is anything other than a huge number? You might think that nobody would even try to argue (that, but you would be wrong. That is exactly why I mentioned this number. Because it is not huge: it is beautifully small. If we even start to think about how tragic each of these deaths is for the parents who had waited for their newborn to smile, and walk, and play, and instead had to bury their baby, then this number could keep us crying for a long time. But who would be helped by these tears? Instead let's think clearly about human suffering. The number 4.2 million is for 2016. The year before, the number was 4.4 million. The year before that, it was 4.5 million. Back in 1950, it was 14.4 million. That's almost 10 million more dead babies per year, compared with today. Suddenly this terrible number starts to look smaller. In fact (2)the number has never been lower. Of course, I am the first person to wish the number was even lower and falling even faster. But to know how to act, and how to prioritize resources, nothing can be more important than doing the cool-headed math and realizing what works and what doesn't. And this is clear: more and more deaths are being prevented. comparing the numbers. (3). We would never realize that without
