1.50 $\displaystyle kg/m^3$ is 1.50 $\displaystyle g/L$
1.50 with one significant number is 2, but you don't lose any significant numbers in the conversion from $\displaystyle kg/m^3$ to $\displaystyle g/L$.
Maybe you should read this article about significant numbers: http://en.wikipedia.org/wiki/Significant_figures
I read the article in it's entirety. I'm just still confused.
1) 0.050 L to mL
I converted and found the answer to be 50 ml so I tried writing as 5 x 10^1
The system said it was wrong
2) 8.0 x 10^-8 m to nm
I converted and found the answer to be 80 nm so I tried writing as 8 x 10^1
The system said it was wrong
I'm still stuck.
Thanks,
