Please Help!! Calculated value of g??
969814
G = 6.67 x 10^11 N.m2.kg-2, a universal constant\nM = 5.9742 × 10^24 kilograms, the mass of the earth\nr = 6378.1 kilometers, the radius of the earth\n\nSo add 390 to r.  G times M divided by r squared is your new g.

Use the atomic weights of the individual elements, and add them together.  For instance, if I had water, H2O:\n\nH - 1.01 g * 2 = 2.02 g\nO - 16.00 g\n\nSo the molar mass of H2O would be 18.02 g/mol.\n\nIf I wanted to convert from grams to moles, I would divide the grams by the molar mass.  Grams cancels out to be left with moles.\n\nIf I wanted to convert from moles to grams, I would multiply the moles times the molar mass.  Moles would then cancel out to be left with grams.

1 G, I dont see how it can be zero otherwise it would float off!\n\nOK call me an idiot...I have just read the other answers lol

http://dbhs.wvusd.k12.ca.us/webdocs/Mole/Grams-to-Moles.html\n\nAbout sums it up.  Find grams (usually given), then divide by molecular mass (grams per mole).

Ok, now this one I can do:\n\nMg3N2  ---> 3Mg (s) + N2 (g)
232086
(5 cm^3)*(8.9)(g/cm^3) = 44.5 g
551802
4w - (gu)/5 = 4u\n4w = 4u + (gu)/5\n4w = u (4 + g/5)\nu = 4w/(4 + g/5)

2 Mg + O2  =  MgO\n48 g  + 32 =   80\n50 g + 33.33= 83.33\n (50*80) / 48 = 83.33\n\nit should have been 83.33\n75/83.33=0.90    = 90% ?

A quick guess without having reviewed your math, try adding g = 9.8 m/sec^2 to your answer and see if that is the answer that is needed.

2x (G2 + M2 ---> 2GM)      DH=-280.0*2= -560.0 kJ\n2x (L + 2M2 ---> LM4)      DH=-350.0*2= -700.0 kJ\n   (L2G4 ---> 2L + 2 G2)   DH=122.0*(-1)=-122.0 kJ (change sign when flip over)\n\nAdd them together, we'll have:\n2G2 + 2L + 6M2 + L2G4 ---> 4GM + 2LM4 + 2L + 2G2\nthen cancel 2G2 and 2L on both side, we end up with:\nL2G4 + 6M2 ---> 2LM4 + 4GM\nthe enthalpy of this reaction is, therefore the sum of each enthalpies calculated above.\nDH=(-560.0) + (-700.0) + (-122.0)= -1382.0 kJ (exothermic process)\nhope that'll help!

°oO****Oo°°oO****Oo°°oO****Oo°\n\n\n 4 ∫[g(x)] g'(x) dx = 4 x 1/2g(x)² +c = 2g(x)²+c\n\nits the first suggestion that u made but i think you forgot the number 4...\n\n\n°oO~<<_P~'*'_ I~'*'_M~'*'_O~'*'~L _~'*'_A>>~Oo°

You mean find "g" as if you didn't know the constant? Okay.\n\nPretty simply really. Have the height measured that you're going to drop it from to where it's going to land (this will be your "h"). Make it a high one (one meter is enough). Measure the mass of the object (that's the "w"). Then when you do the experiment, time it. Start it at the instant you let it drop and stop it once it touches where ever it lands. That's enough information to find "g." Just solve for "g" then that would be the answer.\n\nActually, for an experiment, you should solve for "g" as a formula before you start doing anything else. So the formula would be like this:\n\ng = (2h)/[(t^2)(w)]\n\n(t^2 is "t squared")\n\nSo just have that formula then do the experiment: measure height of the drop, the mass of the object, then time it when you drop it (you need good reflexes when you drop it, as it falls fast).\n\nPS Penguins!!!

g = gram\nkg = kilogram (1,000g) \nmg = milligram (1/1,000g) \nmcg or µg = microgram (1/1,000,000g)

Break it down into three sections determined by the points where the absolute values change sign.\n\nfor 2 < x, g(x) = (x-2) + (x+2) = 2x\n\nfor x < -2, g(x) = -(x-2) + (-(x + 2)) = -2x \n\nfor -2 < x < 2, g(x) = -(x-2) + (x+2) = 4

First of all, we can estimate what the answer is going to be.  About half of all silver is 1 dalton too light, that means that the other half must be 1 dalton too heavy.  So we are looking for an answer of around 108.9.  \n\n(.5184)(106.9051) + (1-.5184)x = 107.9\n\nAnd you solve for X, which I get to be 109.0, which is what we predicted.

U have to use JavaScript for calculations.\nThere is a function 'eval' in JavaScript that takes the operators and operands as input and returns the result.\n\nE.g:  eval(7*5), it will return 35.
