compared with a 1-kg block of solid iron a 2-kg block of solid iron has twice as much?

Assuming the blocks were made from the same batch of iron, they would have the same density. So a 2-kg block of solid iron would have twice as much mass, weight, volume, and potential energy (if the block are the same distance off the ground).

There's no way to tell - it depends on the density of the material tht you're talking about. 900 cubic feet of lead is much heavier than 900 cubic feet of water.

Newtons, or sometimes kilograms

Don't mind the other smart ars*es - the answer is three stone, four kilograms and sixteen ounces.  I tested it twice and can guarantee the answer.

1 kilogram is equal to 2.2 (2.20462) pounds.\nSo for each kilos you times it with 2.2

Gold is VERY heavy, twice the weight of lead. Those movies where people are throwing around gold bricks is far from reality. A cube of pure gold with 14.5 inch sides weighs 2000 pounds!!

=  because 2kL is 2 kiloliters and 2 kiloliters is 2000L or liters

1 kilo = 2.2046 pounds\n\n1 kilo divided by 2.2046 pounds = .453597 kilograms\n\n1 pound = .453597 kilograms

4 Fe(s) + 3 O2(g) ----> 2 Fe2O3(s)\n\nFirst, you have to check if the chemical equation is balanced. In this case, it is. So, what it tells you is that for every 4 mole of iron that is reacted, 1652 kJ will be released to the surrounding. Now, since O2 is in excess, iron will then be your limiting reagent. If you have 3.34 mole of iron, you can use ratio to determine how much energy will be released.\n\nE = (-1652/4) *3.34 = -1379.42 kJ\n\nNote that the "-ve" sign indicates energy is released instead of being absorbed.

Its' probably a rounding error. It would depend on which masses for the elements you use, how precise you want to be.

Both are Same Weight , 1 Kg\nbut Volume is different

E = cp*m * ∆T; you have cp (specific heat), m and ∆T.  Find how many moles 1kg of iron is, and subsitute that for the mass in the formula for cp.  You can get that information here http://en.wikipedia.org/wiki/Iron

1.62 M\n57.15 kg\nGoogle has a real good conversion tool. Just type in the search field, 9 stones in kilo and it will work it out for you.\nBy the way Sam, hope all is working out at home now

they would be almost the same weight, however mild steel should be slightly heavyer
