赤枠で囲った箇所について質問です。 CuSO4(無水物)のモルを求める過程ですが、 題意の結晶は、CuSO4×5H2Oだから、ここに質量の比である "160"をかけるべきではないでしょうか? なぜ解答のようになるのか、教えてほしいです。

5 溶液の性質 次図の容器(a)では、純水とその蒸気が平衡にな っており、10個の水分子(O印) が蒸気となって空間 を満たしているとする。容器(b)では,水分子のうち 1/10 だけをショ糖分子(●印) で入れ替えたとする と、ショ糖分子は不揮発性で蒸気にならないので、 平衡状態で空間を満たす水分子の数は9個となる。 したがって、溶液の蒸気圧Pは,純溶媒の蒸気圧 P。よりも小さくなる。 37 5.00 =0.0200[mol)である。 250 水和物の水溶液の質量モル濃度を求めるとき,水 和水は溶媒に加わることに留意すること。 CUSO,5H.O 5.00g中のH.Oは、 90 5.00× =1.8(g] 08 250 質量モル濃度:0.0200× 1000 =0.196[mol/kg) 100+1.8 (2)電解質水溶液では,溶質が電雛することによっ て,溶質粒子数が増加する。よって,沸点上昇度 At を求めるときは,電離して生じた溶質粒子(分子, イオン)の総物質量により求めた質量モル濃度で考 える必要がある。 A液:CUSO,一→Cu'*+SO-より, 0.196×2=0.392(mol/kg) B液:NaCI-→Na*+CI-より、 O P。 O O P HO=18.0, CO (NH2)2=60.0, CizHz2O.1=342 より, 180 水: 18.0 =10.0[mol),尿素: 6.00 -=0.100[mol), 60.0 1.17 1000 ショ糖: 342 6.84 =0.0200[mol) -×2=0.400[mol/kg) 100 58.5 C液:ショ糖(非電解質) 10.0 (ア) 10.0+0.100 =0.990 6.84 1000 -=0.200(mol/kg) 342 100 10.0 . 最も沸点の高いものは, Bである。 (3) 質量モル濃度の大きい溶液ぼほど蒸気圧降下度が 大きい。したがって,質量モル濃農度の小さい溶液か ら質量モル濃度の大きい溶液へ向かって水蒸気が移 動し,長時間後には各水溶液の質量モル濃度(水蒸 気圧)が等しくなって平衡状態になる。 そのときの濃度は,3つの溶液を混合したときの質 量モル濃度と一致する。 A, B, C内の溶質粒子の総物質量は、 0.0200×2+0.0200×2+0.0200=0.100[mol) A, B, C内の水の総質量は, (イ) 10.0+0.020 =0.998 (ウ)3.13×10°×0.990=3.10×10°(Pa] (エ)3.13×10×0.998=3.12×10°(Pa] (オ),(カ) A液よりB液の方が水蒸気圧が高い。す なわち,A液の液面のすぐ上ではA液の飽和水蒸気 圧を上回る過飽和な水蒸気が存在することになり, 水蒸気の凝縮が盛んに起こる。(平衡にはならない。) 一方,A液への水蒸気の凝縮の進行により,連結管 内部の水蒸気圧はB液の飽和蒸気圧を下回る水蒸気 圧しか存在できない。したがって, B液からは盛ん に水の蒸発が進行する。 (平衡にはならない。) このようなB液からA液への水蒸気の移動は, A 液とB液の質量モル濃度が等しくなり, A液とB液 の飽和水蒸気圧が等しくなるまで続き,やがて, 気 液平衡の状態に達する。 (キ)B液からA液へ移動した水の物質量をn[mol) とする。(A 液の水のモル分率)= (B液の水のモル 分率)になると,水の移動が止まることより, .Jm001 ケ 101.8+100+100=301.8[g) . 平衡状態での溶質粒子の総質量モル濃度は、 1000 0.100× -=0.3313 [mol/kg) 301.8 平衡に達したとき,ビーカーB内で増加した水の質 量をm[g)とおくと 1000 0.0200×2× =0.3313 m=20.7(g) 100+m 10.0+n 10.0-n 溶液の質量は,100+1.17+20.7=121.87[g) . n=6.67[mol) 10.10+n 10.02-n 参考 ビーカーA, B, cでの水の出入り 平衡時,ビーカーA内で増加した水の質量を nlg)とおくと, >70(1) 0.196 mol/kg (2) B, 全溶質粒子(分 子,イオン)の質量モル濃度が最も大きいから。 (3) 122g |解説 160 より,CuSsO,5H:O 5.00g中の CuSO,の物質 量は, 1000 101.8+n n=18.9(g) 0.0400× =0.3313 (1)式量は CuSO·5H.O=250, CuSO。= 同様に,ビーカーC内で減少した水の質量を Plg)とおくと、
