100g/Cm3等于多少kg/m3

100g/cm3 =100×10^-3kg/10^-6m³ =100×10^3kg/m³ =100000kg/m³

(1)∵1ml=1cm3,100ml=100×1cm3=100cm3;∵1cm3=10-6m3,100ml=100cm3=100×10-6m3=10-4m3;(2)水的密度是1.0×103kg/m3=1.0×103×10-3g/cm3=1.0g/cm3.故答案为:(1)100;10-4;(2)1.0×103;1.0.

浓度单位ppm与mg/m3的换算:mg/m3=(M/22.4)*ppm*[273/(273+T)]*(Ba/101325)

1.砂的空隙率=(1-堆积密度为1450 kg/m3/表观密度为2.65g/cm3)*100%=(1-1.45g/cm3 /2.65g/cm3)*100%=45.28302 2.石的的空隙率=(1-堆积密度为1500 kg/m3/表观密度为2.7g/cm3)*100%=(1-1.5g/cm/2.7g/cm)*100%=44.444 3. 50t沙堆积1.2米高需要28.74m...

酒精的密度ρ=800kg/m3=0.8g/cm3,∵ρ=mV∴100g酒精的体积:V=mρ=100g0.8g/cm3=125cm3,所以用量筒测出体积为125cm3,酒精的质量即为100g.故答案为:125.
