    繼續(xù)剛才數(shù)學(xué)題,
    第一題: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?,我只想看我做的對(duì)不對(duì),DENSITY不知道公式.
    第二題: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?這題的DENSITY 又怎么算?以前化學(xué)沒學(xué)好
