It's likely to be adequate.

If you don't have much test gear, you can put a dummy load on one end and a transmitter on the other end, and pour 100 watts into it for a few minutes at ten meters. Then feel it. If it doesn't get warm, it isn't turning your RF into heat. All coax is lossier at higher frequencies -- that's why you do this on ten meters.

If it does get warm, send it to the landfill, or use it as rope for erecting tents at Field Day. That's what the Novices did with 100 feet of brand new Belden RG-58B/U that I made available at Field Day in Dallas one year. Did you know that a muscular young Novice can tie really tight knots in RG-58? It's easier to cut with a pocket knife than rope is, too.

Anyway I'll bet it's just fine.
