avogadro's number (6.022 x 10^23) is the number of atoms in a mole. so the number u gave is equivalent to half a mole of H2O and since one mole of H2O is approximately 18 gr, half a mole will be apprximately 9 gr of H2O

There are 18.06x10^23 molecules and its weight is 132.0285 or the weight of 3 moles of carbon +6 moles of oxygen

simple F=m*a\nm=0.8\na= the acceleration due to gravity (9.8 ms^2)\nWeight is 7.84 N\nthe conversion should be in your textbook from newtons to lbs and from lbs to oz

23.5 X the molcular weight of what ever it is X Avogadro's number (6.0221415 × 10^23 ) = the number of atoms or molecules in 23.5 grams.

Fd = Fd for the sides of the seesaw\n\n23 * 1.5 = 21 * x\nx = ((23 kg) * 1.5 m) / (21 kg) = 1.64285714 meters\nshould be with 2 significant digits: 1.6 m

Well, if you convert grams to kilograms, then you have\n\ne [=] kg*(m^2/s^2) [=] kg*(m/s^2)*m [=] N*m [=] J\n\nHowever, the units of E are determined by the units of mass, distance, and time that you use, and consequently could by in any of the units of energy.\n\nI'm not sure what english units you mean, but                               1 J = .73 feet*pound_force.\n\nFor unit conversions, consider using google or download a more comprehensive freeware unit converter, like Uconeer. I use Uconeer for the more obscure unit transformations, and tabulated values for more common conversions.  Google it.

And I see that you are no exception, as you HAVE confused them!!\n\nIn the S.I. system, mass is kg, and weight is N (that is Newtons)\n\nIn the Imperial system, mass is slugs and weight is pounds.\n\n1 slug is equal to 14.6 kg.\n1 lb. is qual to 4.5 N\n\nPeople generally confuse them because the authorities decided  to equate 1 kg to 2.2 lb.  Not that it makes that much of a difference if these are used for commercial and not technical/scientific purposes, since gravity is basically the same at all habitable places on Earth.

1 inch ~ 2.54 cm\n1 ft ~ 30.48 cm\n\ntechnically, a pound (lb) and grams/kilograms do not measure the same thing. a pound is a measure of weight (a force) while a gram is a measure of mass.  At sea level on earth, where gravity is about 9.81 m/s^2, a mass of 1 kg would approximately have 2.2 lb of weight.  But for basic science classes, this is assumed to be interchangeable

Using 9.8 m/s^2 for gravity, the answer is 3,234 J.

According to Google:\n1 ounce = 28.3495231 grams\n\nYou can double check this if you know that there are about 454 grams in a pound.  454/16 ≈ 28+ grams

hmmm ...\n\n(2.5 x 10^3  ) x (.0685) = .17125 x10^3 = 1.7125 x 10^2 g

A kilogram is 1,000 grams. Therefore you have 25,000 grams.
