例題 36 モル濃度 example problem 2.0mol/Lの水酸化ナトリウム NaOH 水溶液について 次の問いに答えよ。 ただし, NaOH の式 量は40 とする。 ■) 水溶液 200mL中に存在する NaOH の物質量は何mol か。 この水溶液を200mLつくるのに必要な NaOH の質量は何gか。 この水溶液の密度が1.05g/cm3であるとき, この水溶液の質量パーセント濃度を求めよ。 解答 (1) 0.40 mol (2) 16g (3) 7.6% 200 1①200mL= -L 1000 ベストフィット mol をLで割ればモル濃度である。 ②溶液の質量〔g〕=体積 [cm²] × 密度 〔g/cm²]。 解 説 ③ 密度の単位 ■) NaOH の物質量〔mol] =モル濃度 [mol/L] ×溶液の体積〔L〕より g/cm3またはg/mLを 用いる。 200 NaOH の物質量[mol] =2.0mol/Lx L = 0.40mol 1000 2) この水溶液を200mLつくるのに必要な NaOH の質量は, 2.0mol/LのNaOH 水溶液200mLに溶けてい る NaOH の質量である。 (1)で求めた物質量を質量 〔g〕に変換すればよい。 NaOH = 40g/mol より 必要な NaOH の質量〔g〕 = 0.40mol × 40g/mol = 16g 3) 2.0mol/L だから, 溶液1L (1000mL) に NaOH が 2.0mol溶けている。 溶液1Lの質量 〔g〕=1000mL×1.05g/mL=1050g 溶液1L中の溶質の質量 〔g〕 = 2.0mol×40g/mol = 80g より 質量パーセント濃度 〔%〕= 溶質の質量 〔g〕 溶液の質量 〔g〕 x 100= 80g - ×100=7.61 = 7.6 1050g 4D
