0.2 kg = 200 grams
80.0 grams = 80.0 grams
524 mg = 0.524 grams
Total = 280.524 grams
Einstein deduced that mass and energy are equivalent, and that E = mc2 where E = energy, m = mass, c = velocity of light. This of course applies to the actual amount of mass destroyed in a reaction, not to the total masses involved. Thus in a nuclear fission reaction in U-235, only a small amount of the total mass of the U-235 nucleus disappears to form energy, most of it appears in the masses of the two fission fragments, the total energy released is 200 Mev per fission which is about 3 x 10-11 Joules. In a chemical reaction energy is released but at a much smaller proportion of the masses involved. Bearing this in mind you can see that the total energy in objects around us is truly awesome! You can work out some figures, use kilograms for mass and meters/sec for c, E will then be in Joules.
The combined weight is approx 6.7 Newtons.

Grams. * * * * * That is total rubbish. Grams is a measure of mass, not volume. Volume may be measured in cubic centimetres ( 1 cc = 1 millilitre) for small objects, litres for medium sized objects to cubic metres for "normal" large objects and cubic kilometres for mountains or bigger.

total grams is required. 55% of what total quantity?
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
Remains constant.
7.5 grams of ammonia contains approximately 4.5 grams of nitrogen. This is calculated by multiplying the molar mass of nitrogen (14 g/mol) by the number of moles of nitrogen in ammonia (1 mole) and then converting to grams.

Sodium bromide (NaBr) has a weight of 102.89 grams per mole. Determining the mass of NaBr in a mixture can be calculated if the constituent weights of all the others are known. The total masses of the knows can be subtracted by the overall weight to isolate the mass of NaBr.
To find the total volume of ethanol, you would need the density of ethanol. Using the formula: volume = mass / density, you can calculate the volume of ethanol by dividing the total mass by the density of ethanol.
Five grams of saturated fat in a chicken leg (thigh plus drumstick), 19 grams total fat.
The formula for sulfate is SO4, which indicates that there is one sulfur atom for every four oxygen atoms (1:4) ratio. If this isn't what you're looking for, then perhaps you're looking for specific percentages. In that case, you need the atomic masses of the elements involved to find the total molecular mass.Sulfur = 32.1 gramsOxygen = 16.0 grams × 4 atoms = 64.0 grams----------------------------------------------------------Sulfate = 96.1 gramsThen you take the mass of each and divide it by the total mass to get a percentage.32.1 grams ÷ 96.1 grams = .334 = 33.4% sulfur in sulfate64.0 grams ÷ 96.1 grams = .666 = 66.6% oxygen in sulfate
Following the law of conservation of mass, also 10.0 grams.
