继续刚才数学题,
第一题:A 17.6-gram sample of metal is placed in a graduate cylinder containing 10.0cm^3 of water.If the water lvl rises to 12.20cm^3,waht is the density of the metal?,我只想看我做的对不对,DENSITY不知道公式.
第二题:A container of gas with a pressure of 101 kPa has a volume of 324cm^3 and a mas of 4.00g.If the pressure is increased to 404kPa,what is the density of the gas?Pressure and volume are inversely proportional?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
