To convert between g and kg you just need to know that 1 kg = 1000 g.  If you know your metric conversions, these become very easy!  One "kilo" of anything is 1000 of that base unit.  So 1000m = 1 km as well.  So to find out how many grams 8.2 kg is just think: \n\n8.2 kg X (1000 g/ 1 kg) = 8,200 g

OK...You can start with the equation of DG (I'm using D instead of writing "delta").\n\nDG = DH -TDS  You've seen that equation, right?  OK..Since the boiling point of water is 100 degreed C at 1 atm pressure, we are really talking about an equilibrium situation.  So, DG= 0.\n\nConsequently, DH = TDS.  \n\nSince you know DH and you know T (in Kelvin), you can calculate DS.  Make sure that you convert DH into Joules (instead of kilojoules) before you finish the problem.

I'll give you a hint.\n\nDelta G = Delta H - T Delta S\n\nUsing that formula, you can get 1\n\n(B) you can look up in any physical chemistry text:\n\nG(2) - G(1) = a formula I don't have available

So they told you the relation is:\nd=kh\n(Since they said "varies directly", there is no offset: d=kh+d0)\nThen: 8.45=6.5k\ntherefore k=1.3 (unitless, ft/ft)\n\nThen you want to find:\nd=5.2 = kh=1.3h\nTherefore:\nh = d/k = 5.2/1.3 = 4 ft

There are several wrong answers in the preceding.\nThese are correct:\n\n(lbf) = (lbm) * (acceleration in g)\n(lbf) = (slugs) * (acceleration in ft/sec^2)\n\n1 g = 32.174 ft/sec^2\ncorrespondingly\n1 slug = 32.174 lbm\n\nIf you know acceleration in in/sec^2, the corresponding unit mass would be 12 slugs or 386.09 lbm. This unit does not have a popular name that I am aware of.\n\n1 lbm = .45359 kg\nAll conversions are approximate

Use the formula: Density equals Mass divided by Volume\n\nor\n\nD=M/V\n\nSo we plug in numbers from your question:\n\nD = 23g/25 cm^3\nD = 0.92 g/cm^3\n\nor .92 grams per cubic centimeter.

braxton_paul is a little mixed up.\n\nUsing an electronic scale accurate to 1/10 of a gram, I found the mass of a penny (from 2002) to be 2.5 grams.

2.2 gram\nu can calculate it by the molarity formulae

deltaG = deltaH - TdeltaS\n\nWhen delta G equals zero,\n\ndeltaH = TdeltaS\n\ndeltaS = deltaH/T  = (44.0 kJ/mol)/373K = 0.11796 kJ/mol.K\n\nSo I'd pick e.

This sounds more like arithmetic than math, except that the last 2 questions also involve units of measurement. Without doing the arithmetic, I'll tell you that the answer to #2 will be density in g/ml. (Yes, answerer 3, you can divide g by ml; what you can't do is add/subtract dissimilar units!) The answer to #3 will be volume in cm^3.

D = M/V\n\nDensity= Mass/Volume

ya you would just go density divided by the mass and then you get the volume  make sure you density is grams/ml and then your mass should be ml and then your volume would turn out to be grams. good luck
