The conversion factor you need for this problem is the atomic mass of arsenic.
74.9 gram arsenic = 1 mole arsenic
Since you want to end up in units of moles of As, this goes in the numerator (on top). You want to convert from grams As, so this goes in the denominator (on the bottom).
grams As1 mole As = moles As74.9 gram As
The conversion factor you need for this problem is the atomic mass of titanium.
47.9 gram titanium = 1 mole titanium
Since you want to end up in units of grams of Ti, this goes in the numerator (on top). You want to convert from moles Ti, so this goes in the denominator (on the bottom).
moles Ti47.9 gram Ti = grams Ti1 moles Ti
The conversion factor you need for this problem is the atomic mass of rubidium.
85.5 gram rubidium = 1 mole rubidium
Since you want to end up in units of moles of Rb, this goes in the numerator (on top). You want to convert from grams Rb, so this goes in the denominator (on the bottom).
grams Rb1 mole Rb = moles Rb85.5 gram Rb

No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
U-238 (Uranium-238) has 92 Electrons
Uranium-238 has 146 neutrons.
146
Atomic mass of Arsenic = 74.9g/mol Using the formula: mass = Atomic mass x number of moles mass = 74.9g/mol x 238 mol = 17826.2 grams
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238

1 mole of NaCl: Na = 1 * 22.99 g = 22.99 g Cl = 1* 35.45 g = 35.45 g Total = 58.44 g 238 g NaCl * (1 mol NaCl/58.44 g NaCl) = 4.07 mol NaCl There are approximately 4.1 moles in 238 grams of sodium chloride.
238 grams of water is approximately 47.6 teaspoons.
That is approximately 1.05 cups
238,000,000 micrograms, algebraic steps below: 238 g*1 micrograms 1.0E-6 g=238,000,000 micrograms
238 grams is mass, and cups are a measure of volume. The answer would be different for various substances based on their density (liquids, powders, foods).
There are 453.59 grams in a pound of raw beef. Exactly the same number of grams in a pound of plutonium 238!
238 grams = 8.4 ounces.238 grams = 8.4 ounces.what is 238 grams equal to in ounces?
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
Nothing on a measuring cup can be 'equivalent' to a gram measurement, no matter what system of units the cup is marked in. The cup is marked off in 'volumes', but 'gram' is a measure of mass or weight. The same volumes of different substances can have different weights, so you never know how much volume 238 grams will fill. Take 238 grams of air ... it might fill most of a whole room. Take 238 grams of water ... it'll fill about 238 cc, or 0.238 liter, or 8.05 fluid ounces. Take 238 grams of lead or stones ... it'll fill only a small volume. All of them have the same weight ... about 8.4 ounces. So you might find a mark on a scale equivalent to the weight of 238 grams, but not on a measuring cup.
