Plan on three to four ounces of uncooked spaghetti per person. For 150 people, this is 28-38 lbs uncooked pasta.
Adjust based upon nature of your guests and other meal choices. If you are feeding the football squad and have few side dishes then you may need twice as much.
If you are feeding a couple busloads of 2nd graders on a field trip and have other dishes available then you could probably do half as much.
For reference, the Armed Forces Recipe guide for spaghetti w/meat sauce calls for 12 lbs of uncooked pasta to serve 100 portions of 1 cup each. That's about two ounces per person--and I can tell you from experience that it is not enough.

i need to know how much hamburg,SAUCE,NOODLES for 150 servings
yes
At 100 grams per person, 70,000 grams
150 lbs
75 grams per person, so 7.5 kilos plus sauce
About 150 grams is stored in liver and about 150 grams is stored in muscles.
24 oz of spaghetti cost $2.87
24 oz of spaghetti is a pound and a half.
It weigh about as much as a bowl of spaghetti
One serving of spaghetti has about 200 calories in it, 160 for a tomato sauce, 100 for butter, and 150 for a slice of garlic bread. (These are averages for what is usually in a spaghetti dinner and are correct for the serving size of that type of food.) So that's 200,160,100, and 150, for a total of about 610 calories or so for the entire meal, which is quite little, considering.
If you plan for 6 oz per person, that would be 300X6=1800 oz / 16 = 112.5 pounds.
