What statement best compares the masses of the two samples?
The masses cannot be compared without a balance.
Would the masses be identical if you measure the exact measure of carbon dioxide and water entered a plant and sugars produced?
no
An objects what is a measure of the amount of matter on the object compared to known masses?
mass
What is the molecules of an ideal gas?
Perfectly elastic collisions, point masses (no volume of individual molecules), no intermolecular attractions.
Does each system kilograms and pounds measure the same quantity?
Yes, now. In the past there were different "standard" masses.

How do you calculate the center of gravity?
By taking the weighted average of all the individual masses. If the masses are distributed (as opposed to point-masses), integrals must be used.By taking the weighted average of all the individual masses.

When hail occurs what is going on with the air masses?

To increase the force of gravity between two objects how should you change the masses?
Increase the masses.
What does the metric system help scientists do?
measure objects, masses. and liquids.
What object's is a measure of the of matter in the object compared to known masses?

no
Who was in charge standardizing the atomic masses of the individual elements?
George Washington carver
Will averaging something make the measurement more accurate?
Only if the items being measured are all identical. Otherwise you will lose the variation between individual items. It would be sensible to measure the mass of ten identical coins and take their average as a measure of the mass of a coin. But the average mass of ten people is not a more accurate measure of any of their masses.
