Chemistry Senior High 7 monthsago (1)で、黄色の線を引いてあるところを0.3molにしたら、アルミニウムの質量か8.1gになり答えが合いませんでした。なんで、分数のままにしているんですか? 例題 36 物質量 次の問いに答えよ。 ただし, アボガドロ定数は6.0×102/mol とする。 (1)アルミニウム原子 2.0 × 10% 個の質量は何gか。 (2)窒素 N2 が 56.0gある。 この気体の体積は標準状態で何Lか。 解答 (1)9.0g (2) 44.8L example problem 11mol = 6.0×1023個 ベストフィット まず物質量を求め,次に質量や体積を求める。 1mol = 原子量・分子 量・式量g 解説 1 mol = 22.4L 2.0×1023 (1) アルミニウム AIの物質量 [mol] = = 6.0 x 1023/mol Al=27g/mol より,アルミニウムの質量[g] = 1/2 (2)N2=28g/mol より 窒素 N2の物質量[mol] = 3 =1/23molである。 mol × 27g/mol = 9.0g 56.0g 28g/mol =2.00molである。 標準状態で1molの気体の体積は22.4Lなので, 窒素の体積 [L〕=2.00mol x 22.4L/mol = 44.8L = Solved Answers: 1
English Senior High 7 monthsago なぜ赤線のように書いてあるのに、③が間違っているのか教えてほしいです🙏 Curious about this trend, I found a recent online survey conducted among 3,000 Japanese middle school students and their parents. The results were surprising. Nearly 50% of the students admitted (that they played video games after they were supposed to go to bed. More than half said (they tended to do their homework after playing video games. Far more boys than girls had played video games at home when they were absent from school. Additionally, most students reported that their parents never take away their games to control their playing time. Solved Answers: 1
