To find this, you simply multiply the number of moles by avogadro's number which is 6.22 X 10^23.
3.1 x 6.022x10^23 = 1.9 x 10^24 atoms of sulfur.
Sulfur-31 is the isotope with 16 protons and 15 neutrons.
Zn + H2SO4 -> ZnSO4 + H2 I assume zinc limits? 31. 8 grams Zn (1 mole Zn/65.41 grams)(1 mole H2/1 mole Zn)(2.016 grams/1 mole H2) = 0.980 grams hydrogen gas
Yes it does. ALL diesel has at least a little bit of sulfur in it; sulfur is in all crude oil. They could remove all the sulfur from diesel, but a slight amount is left in because it lubricates the engine. Low-sulfur diesel contains no more than 500 parts per million of sulfur. This fuel is legal to use in any engine made on or before December 31, 2006. Ultra-low-sulfur diesel contains no more than 15 parts per million of sulfur. This fuel is required for all engines made after January 1, 2007, and you can use it in any diesel engine.
The sulfur atom has 16 protons and 16 electrons.The three stable isotopes of sulfur differ in their neutron number:Isotopes with mass number -32, -33 or -34 have 16, 17 or 18 neutrons respectively. The isotope with mass number 32 is the most abundant natural isotope.

31 grams CH2O (1 mole CH2O/30.026 grams)(2 mole H/1 mole CH2O)(6.022 X 1023/1 mole H) = 1.2 X 1024 atoms of hydrogen =======================
There are 31 atoms total in penicillin.
MgF2 has a molecular weight of 24+19*2 = 62g. Thus, 31 grams of MgF2 represent .5mol. There are 6.022*10^23 particles per mole. Since MgF2 has three atoms in it, we can find the number of atoms by the following: (.5 mol)(6.022*10^23 particles/mol)(3 atoms in MgF2) = ... Enjoy your free high school chemistry answer!
Molar mass = 31+ 5(35.5) = 208.5 g/mole divide ... 35.6 g / 208.5 g/mole = 0.171 mole
The atomic mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.
The True Confessions of Adrian Albert Mole was created on 1989-08-31.
The gram atomic mass of titanium is 47.867. Therefore, in a 0.65 mole sample, there will be 0.65 X 47.867) = 31 grams, to the justified number of significant digits.
Each sulfur atom contains 16 protons; the mass number is the sum of the numbers of protons and neutrons; therefore, 47. (It is unlikely that such a heavy isotope of sulfur actually exists.)
Copper-31. All atoms with 29 protons are Copper.
Sulfur-31 is the isotope with 16 protons and 15 neutrons.
Hans Moleman is actually 31 years old but looks elderly.
The formula for the formula unit of anhydrous iron (III) acetate is Fe(C2H6O2)3. Tally the atoms as follows: Multiply the subscript within parentheses by the subscript after the parentheses to obtain 6 carbon atoms, 18 hydrogen atoms, and six oxygen atoms; add the one atom of iron (implied by lack of any subscript immediately following it); the total is 31 atoms.
