1. The problem statement, all variables and given/known data
I am giving .15Mo/pc^3 how can i convert that into g/cm^3
mo is solar mass and its in grams and pc is distance so its in cm so wht would i do to convert it?


2. Relevant equations



3. The attempt at a solution
would i just mutiply .15 by the solarmass(1.9e33g) than divide by pc^3 which is (3e18 cm)
so would i do .15((1.9e33/(3e18^3) ?

hi leonne! :smile:

(try using the X2 icon just above the Reply box :wink:)

i assume you mean .15((1.9e33/(3e18)^3) ? :wink:

yes, that's correct …

in dimensions questions like this, you use the conversion factor to the same power as the unit appears it the formula :smile:

(if it makes you happier, you can check it by writing 1 Mo/pc3 = 1 (Mo/g) (cm/pc)3 g/cm3 :wink:)
