問一で、二枚目の写真のように計算すると書いてあったんですが、水50ミリリットルで計算してて、水酸化ナトリウムの固体2gは足さずにやってるんですけど、それって大丈夫なんですか? 反応熱×モル×10³=質量×比熱×温度変化という式でやってます。これの質量の部分です。

ーー 水生いいだ 人eyewiropxeex 問1ご4に答えよ。 を北導を42/grよ 度を 1g/cm)とし, 原子量はH=1, 0=16, Na= 23, 各実験での体積の変化はないも のとする。 実験1 水50mDを入れた過熱容器0に水本化ナトリウムの個体208を加え完全に浴かす と. 水溶液の温度が180Cから286やに上昇した。 9 実験2 断熱容器()に80Cの.0molル塩酸50mじを入れ.
