继续刚才数学题,
第一题:A17.6-gramsampleofmetalisplacedinagraduatecylindercontaining10.0cm^3ofwater.Ifthewaterlvlrisesto12.20cm^3,wahtisthedensityofthemetal?,我只想看我做的对不对,DENSITY不知道公式.
第二题:Acontainerofgaswithapressureof101kPahasavolumeof324cm^3andamasof4.00g.Ifthepressureisincreasedto404kPa,whatisthedensityofthegas?Pressureandvolumeareinverselyproportional?这题的DENSITY又怎么算?以前化学没学好
我自己的中文翻译也不好呀
