The density of a liquid in CGS system is 0.625g//cm^(3). What is its magnitude in SI system?

Answer»

`625kg//m^(3)`
`0.0625kg//m^(3)`
`0.0625kg//m^(3)`
`0.00625kg//m^(3)`

Solution :DENSITY `=0.625g//cm^(3)`
`1g=10^(-3)kg`
`1cm=10^(-2)m`
`therefore"Density"=(0.625xx10^(-3))/((10^(-2))^(3))`
`=0.625xx10^^(-3)xx10^(6)`
`=0.625xx10^(3)=625kg//m^(3)`
