the denisity of "dry ice" is 1.20g/mL.carbon dioxide gas having a mass of 1.20 has a volume of 670mL under standard conditions of temperature and pressure. calculate the percentage of the total volume of the gas which is occupied by particles.
PS answer=0.149%

a mass of 1.20g~~
670ml*1.2g/ml=804g
百分比 1.2g/804g=0.149%
670ml*1.2g/ml=804g
1.2g/804g=0.149%
“干冰” denisity是1.20g/mL.carbon有二氧化物的气体大量1.20有670mL的容量在温度和压力的标准条件下。 计算气体的总容量的百分比由微粒占领。
