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

How many atoms in 1 gram of uranium?
Depends on the isotope. Most uranium found naturally is U238 and hence 238 g would be 1 mole. U235 used for fission and bombs would be 235g.
If you start with 60 atoms of uranium - 238 how many remain after 4470000000 years?
30 atoms
How many atoms make 1 gram of iron?
The number of particles (atoms or molecules) in a substance is known as Avogadro's constant and is 6.02 x 1023 particles per mole. The mole is the amount of a substance that contains the same number of particles as the number of atoms in 12 grams of carbon-12. If we consider uranium 238 as the largest isotopic component of natural uranium, and as it consists of atoms not molecules, then 1 kilogram contains 1000/238 moles (1000 grams the mass, 238 the relative atomic mass), ie 4.20 moles. so the number of atoms will be 4.20 x 6.02 x 1023, or 2.529 x 1024 atoms.
How do you write half life of uranium 238 as a standard number?
The half-life of the isotope uranium-238 is 4 468 000 000 years.
What is the highest sub level electron occupy in uranium 238?
The highest sub level electrons occupy in a Uranium-238 atom is a f-sub level.
How many grams in 238 moles of arsenic?
The conversion factor you need for this problem is the atomic mass of arsenic.74.9 gram arsenic = 1 mole arsenicSince 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
How do you solve for how many grams are in 2.38 moles of calcium carbonate?
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
Is 238 gram bigger than 237ml?
Both the terms gram and ml is different from each other; and correlated with density. When we multiply volume into density then we get mass of that body. So whether or not 238 gram is bigger than 237ml is totally based on the density of that body.eg: for mercury(density-13.6gm/ml), weight of 238 gram is lesser than 237 ml.for oil(density-0.9gm/ml), weight of 238 gram is bigger than 237 ml.
How many moles of NaCl is 43.83grams of NaCl?
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.
