My daughter's science homework is to find the mass & volume of 4 items that you can buy in a grocery store. She knows how to find the volume but is stuck on how to find the mass. My brain is too old to remember so how would someone find the mass on, let's say a box of South Beach Diet Snack Crackers, whole wheat? She's only in junior high, & like I said, my brain is too old so if someone can exp0lain this to me in simple jr. high english I would appreciate it. This way I can try and explain it to her.
Thanks!

rh gave you some slightly erroneous info. the label weight is the mass of the contents of the container, not the entire mass, so you would have to weigh the item in its container to get the mass. For things in cardboard or plastic, there wont be much difference, but something in a glass or steel (tin can) container will have quite a higher total mass than the label figure.

Mass Of Object

To find the mass of an object you could weigh it, then divide by the gravitational acceleration.
Weight = mass * gravity
If the object it too light to be weighed on a scale you have around the house/kitchen, you could try weighing multiple identical items, then dividing by the number to get the weight per item.
Keep the units of mass in mind.
The Kilogram is the SI unit of mass. The Newton is the SI unit of weight. Gravitational acceleration = 9.81 m/s^2.
Using the US/imperial system, the pound is the unit of mass and the slug is the unit of weight. Gravitational acceleration = 32 ft/s^2.
Weight does NOT equal mass.

A balance is good, however you could also use the displacement of water. Fill a container with water all the way to the rim. Place the container in a bowl, or something to catch the water. Submerge the object completely until it is just under the surface and your finger is just in the water. The water that is displaced (overflows into the bowl) is the volume of the object. Measure the this volume in ml. One ml of water is equal to approx 1g (approx because the water is not distilled/deionized). So if an object displaces 25 ml water it weighs about 25 g.

Well, you could weigh it. Is there any other relevant information? Like size, density, anything like that? There's not enough information so I can't come up with any numbers.

The mass is equivalent to the weight, which is printed on the package. If a box of crackers is one pound (454 grams), then the mass is 454 grams. (It is not one pound, because the pound is a unit of force, not mass. But I am being picky.)
