the answer i came up w/ is 1.76g/L. is this correct?

if i'm using PV=nRT, and manipulate that formula to V=nRT/P to find the volume, do i use 44.01g as my molar mass of CO2 and convert that to moles to find 'n'? i'm really confused how to do this b/c it's not at STP.

Where do you get the original amount and the quantity from? I am confused since the problem doesnt have anymore numbers than 18

Suppose a quantity is halvd every 18 years. use the approximate half-life formula to estimate its decay rate. is the half life equation y= 1/2^t1/2 2^1/2t= 1/y t 1/2= log2 (1/y) Where do I put 18 at?

So would your doublexdoublexdoublexdouble=16 be 2 x 2 x 2 x 2= 16??? I am a liitle confused on why you used double?
