Questão 5. Como estudamos no Módulo 2, alguns produtos cosméticos de ação esfoliantes apresentam em sua
composição microesferas plásticas que podem apresentar diâmetro variando entre cerca de 1 a 5 mm. Embora essas
microesferas sejam consideravelmente pequenas, elas são "grandes" quando comparadas às estruturas formuladas
em escala nanométrica. Suponha que uma microesfera de 1 mm de diâmetro va ser dividida em diversas microesferas
de 1 nm de diâmetro. Calcule o número de microesferas em escalas nanométricas que podem ser obtidas a partir do
procedimento descrito.
