高校化学基礎です。 下の問題の、赤線を引いた部分なんですけど、モル濃度を求める問題なのに、物質量を求めて、その求めた物質量が答えとなっているんでしょうか？？ どなたか解説お願いします🙏

えよ。 重要例題 8 濃度 結晶の析出 N=14,O=16, K=39 問1 質量パーセント濃度が20%の硝酸カリウム KNO。 水溶液のモル濃度は何mol/L か。最も適 当なものを、次の①~⑥のうちから一つ選べ。ただし、溶液の密度を1.1g/cm とする。 ① 0.20 ② 0.22 ③ 1.0 ④ 1.1 ⑤ 2.0 ⑥ 2.2 [2015 追試〕 問2 図は硝酸カリウム KNO の温度による溶解度の変化を表している。 60℃の水 100g に硝酸 カリウムを 90.5g 溶かし,この水溶液を30℃に冷却した。このときに析出する硝酸カリウムの 質量とその物質量の組合せとして正しいものを,次の①~⑤のうちから一つ選べ。 質量[g] 物質量 [mol] ① 50.5 0.50 50.5 1.0 70.0 0.50 70.0 1.0 101 1.0 溶解度〔g/100g 水] 40 8110 30 60 温度[℃] 0 考え方 問 1 KNO3 ント濃度 水溶液 1L の質量 質量パーセ水溶液 1L → 中の KNO の質量 モル質量 水溶液 1L 中のKNO の物質量 KNO3 水溶液 1Lの質量は, 1L=1000cm3 より 1.1g/cm×1000cm=1100g この水溶液に含まれる KNO3 の質量は, 20 1100g× -=220g 100 したがって, KNO3の物質量は, Note 問2 グラフより, 60℃で水100g に KNOは110g 溶けるので,加えた 90.5g はすべて溶ける。 また, 30℃で水100g に 40g 溶けるので,この水溶液を 30℃まで冷却すると, 水溶液中に KNO3 は 40g 溶 けている。 したがって, 溶けきれずに析出した KNO3 の質量は, 90.5g-40g=50.5g KNO3 のモル質量が 101g/molであるので,KNO の物質量は, 50.5 g = 0.500 mol 220g_ =2.17...mol≒2.2mol 101g/mol よって,モル濃度は 2.2mol/L。 FIT 101g/mol 解答 問1⑥ 問2① 第2編 物質の変化
