問2と問4の計算の仕方を教えてください赤く書いてあるのが答えです🙇‍♀️

6 水溶液の性質に関する実験を行った。 図は物質A 図 と物質Bの溶解度曲線である。 あとの問いに答え なさい。(2021 富山) < 実験1> 250 ア 60℃の水 200gを入れたピーカーに物質Aを 300g加えてよくかき混ぜたところ, とけきれ ずに残った。 イ ビーカーの水溶液を加熱し, 温度を80℃まで 上げたところ、 すべてとけた。 の 200 と 150 100 50 G0 100gの水にとける物質の質量は 物質 A 物質 B. 0 20 30 40 60 水の温度(℃) 90 80 16 100 ウ さらに水溶液を加熱し、沸騰させ、水をいくらか蒸発させた。 水溶液の温度を30℃まで下げ,出てきた固体をろ過でとり出した。 〈実験2> オ新たに用意したピーカーに60℃の水 200gを入れ, 物質Bをとけるだけ加えて飽和水溶液をつくった。 カオの水溶液の温度を20℃まで下げると,物質Bの固体が少し出てきた。 問で温度を80℃まで上げた水溶液にはあと何gの物質Aをとかすことができるか、図を参考に求めなさい 問2 エにおいて、 ろ過でとり出した固体は228gだった。 ⑦で蒸発させた水は何gか,求めなさい。 ただし, 30℃における物質Aの溶解度は48gである。 -48 70 50 180 問3 土のように,一度とかした物質を再び固体としてとり出すことを何というか,書きなさい。 再結晶 問4 木の水溶液の質量パーセント濃度は何%だと考えられるか。 60℃における物質Bの溶解度を39gとして 小数第1位を四捨五入して整数で答えなさい。 28
