Para resolver essa questão, precisamos entender o que significa "um centésimo de milésimo" da medida oficial do número de Avogadro, que é aproximadamente \(6,022 \times 10^{23} \, \text{mol}^{-1}\). Um centésimo de milésimo é \(0,001\) ou \(10^{-3}\). Portanto, precisamos calcular: \[ \frac{6,022 \times 10^{23}}{1000} = 6,022 \times 10^{23} \times 10^{-3} = 6,022 \times 10^{20} \] Agora, vamos analisar as alternativas: A) \(6,022 \times 10^{18}\) B) \(6,022 \times 10^{19}\) C) \(6,022 \times 10^{20}\) D) \(6,022 \times 10^{21}\) E) \(6,022 \times 10^{22}\) A alternativa que corresponde ao cálculo que fizemos é a C) \(6,022 \times 10^{20}\). Portanto, a resposta correta é a letra C.

Para responder a essa pergunta, é necessário entender a importância do número de Avogadro e como ele está relacionado com a quantidade de entidades elementares em uma molécula. Atualmente, o número de Avogadro é aproximadamente 6,022 x 10^23 mol^-1. Considerando a diferença mencionada na medida feita pelos cientistas, que é equivalente a apenas um centésimo de milésimo da medida oficial do número de Avogadro, precisamos calcular essa diferença. Um centésimo de milésimo é equivalente a 10^-4 da medida oficial. Portanto, para calcular a diferença, fazemos: 6,022 x 10^23 + (6,022 x 10^23 x 10^-4) = 6,022 x 10^23 + 6,022 x 10^19 = 6,022 x 10^23 + 60,22 x 10^19 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x 10^21 = 6,022 x 10^23 + 6,022 x
