Convert `6.4 x 10^5 g m^(-3) ` to correct SI units.
Convert a density of 6.4 × 105 g m−3 to a value in the correct SI unit for density. You should give the answer in scientific notation and to the correct number of significant figures and you should include the symbols for the correct SI unit as part of the answer.
6.4 × 10^5 g m^-3
The SI unit for density is `(kg)/(m^3)` , so we need to convert grams to kilograms, and we already have cubic meters.
`6.4x10^5` grams is equivalent to `6.4x10^2` kilograms,as 1000 grams is equaivalent to 1 kilogram.
Thus `6.4x10^5 g/(m^3)` is equivalent to `6.4x10^2(kg)/(m^3)`
