Can someone please check my answer for chemistry

Compelete the following table for an ideal gas.

P= 7.74*10^3 Pa
V= 10.3 mL
N= ?
T= 25°C

I'm getting 3.20e-4, but my online homework says its wrong, what am I doing wrong?

  1. You didn't show your work so I don't know what you're doing wrong. Perhaps nothing more than punching the wrong button?
    PV = nRT
    7.74kPa x 0.0103L = n*8.314*298K
    n = 3.22E-5 moles
