1 のようなサッカーボールのような形をした、 炭素原子 60 個どだけからなるフラーレン と呼ばれる Ce分子がある。この分子は、 室温では、図 2 のように立方体の項点と、面の中 心に Cs分子が 1 個ずつ位置する結晶構造をと り、その単位格子の一辺の長さは、 1.4nm で ある。なお、熱運動により、室温では、Ce 分子は図の位置で自由に回転 し、球形であると みなせるとする。 また、。』 Ge 結漠 w に均一に 8.4g になった 炭素 C の原子量を 12、カリウム丈の原子量を 39 とし、1.45=2.8,。 アボガドロ定数を 6.0x 10S mot とする。 3 著作物につき図は公開していません。 (DTMiller, Inorganic Materials Chemistrw Oxford University Pxess より転載) 敵1 2のように分子が配列している単位格子をどう呼ぶか、答えなさい。 間2 単位格子内に含まれる Ce分子の数はいくつあるか、答えなさい。 間3 単位格子内の炭素の数は全部でいくつあるか、答えなさい。 問4 Ce結晶の比度はいくらになるか、単倍を g・cm3として答えなさい。 問5 下線(において、単位格子内において 1 個の Ce分子に対して何個のカリウム原 子が含まれているか、もとめなさい。 -
