Convert 3.00 grams of sodium into atoms {show work }

Mol of Na =  
 
                =  
 
                =  0.13 mol

# atoms of Na =  mol ×  avogadro's constant
  
                       =  0.13 mol  ×  [6.02 × 10²³]
 
                       =  7.83 × 10²²

I think you use PV= nRt.

So P=1000
V=25
We are trying to find the moles so n is blank.
R=0.08206
T=1195

This means that your equation is:

(1000)(25) = (n)(0.08206)(1195)

So you are gonna divide each side by (0.08206)(1195) because you are trying to get the moles by itself.

(0.08206)(1195) is gonna cancel each other out, so your new equation is going to be:

(1000)(25)/0.08206/1195 = n

Put that into your calculator and you get:

n= 254.941532

or 254.94moles

If i’m wrong please correct me.
