how much dnp to put into the cap

Heya guys, so I have a curios question: Now with DNP capping everyone says to use the size 0 or 00 caps but its seems to be such a big process with the measuring and large room for error that it opens up. Keep in mind fuck up can = death. so crystal dnp has a weight of: 0.843 g/mL at 20 °C...
