Artigo:

Neste estudo, foram determinados dados experimentais de densidades de soluções líquidas binárias de glicerol + metanol, ou + etanol, ou + 1-propanol, ou + 2-propanol, ou + 1-butanol, em toda faixa de composição, a diferentes temperaturas e à pressão atmosférica. As temperaturas estudadas foram: 288,15 K, 293,15 K, 298,15 K, 303,15 K e 308,15 K. As densidades foram determinadas usando um densímetro de oscilação mecânica da marca Anton Paar (Modelo DMA 4500). Os resultados experimentais foram usados para calcular o volume molar
