[leonne]

Homework Statement

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?

Homework Equations

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!

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

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

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