下の写真の条件で酸化銅15gと炭素粉末0.90gを測り取り同様の実験を行った。反応後の試験管には赤色の物質と黒色の物質が混ざっていた。反応後の試験管内にある固体の物質の質量は合計何gですか? 答えは12.6gでした。 考え方が分かりません。よろしくお願いします、

試験管B 石灰水 反応後の試験管内にある 固体の物質の質量[g] 4 一定量の酸酸化銅に炭素がどれだけ反応するかを調べるため, [実験1], [実験2] を行った。 次の問いに答えなさい。 図1 酸化銅と炭素の粉末の混合物 [実験1] 酸化鋼(黒色)6.0gと乾燥した炭素 の粉末(黒色)0.15gとをはかり取り、 これらをよく混ぜ,試験管Aの中に入れ た。この試験管にガラス管つきのゴム栓 を取りつけ、図1のような装置で十分に 加熱したところ, 試験管A内に赤色の物 質ができた。また, 気体が発生し、試験 管B内の石灰水が白くにごった。気体が 発生しなくなってから, 加熱をやめ, ガラス管を石灰水からぬいて,ゴム管を目玉クリ ップでとめた。試験管が冷えた後,試験管A内にある固体の物質の質量を測定した。 0 試験管入 図2 次に,[実験1] と同様の実験を酸化銅の質 量6.0gは変えずに, 炭素粉末の質量を0.30 g,0.45g,0.60g, 0.75g, 0.90gと変え それぞれ行った。 図2は, 横軸に加えた炭素粉 末の質量を、縦軸に反応後の試験管内にある固 体の物質の質量をとり, それぞれの結果をグラ フに表したものである。なお, 酸化銅と炭素粉 末が過不足なく反応するのは, 酸化鋼6.0gと 炭素粉末0.45gをよく混ぜて加熱した場合であ り,反応後の試験管内にある気体の質量は無視 できるものとする。 [実験2] 6.0 5.8 5.6 5.4 5.2 5.0 4.8 4.6 0 0.15 0.45 0.60 05 0.90 0.30 加えた炭素粉末の質量 [g]
