  • Divide the atoms by Avogadro’s number 6.02 x10 E23

    That will give you moles of sulfur. Multiply that by 32, the molecular mass of sulfur, to get the grams

  • The number of atoms in a mole of any substance is Avogadro’s number (6.02 x 10^23). Given a mass of 3.09 , divide by 6.02 x 10^23 to see how many moles you have.

    3.09 / 6.02 = 0.51 = 5.1 x 10^-1 (You moved the decimal point in .51 to a number between 1 and 10 which was 5. You moved it to the right making it a bigger number. To go back to the way is was, you would be making it SMALLER so your power of 10 is a NEGATIVE number – in this case -1.) Add 10^23 + -1 = 10^22. So the number of moles is 5.1 x 10^22 Now to find the mass of sulfer in grams, the periodic table says that 1 mole of sulfur weighs 32.07 grams per mole. Multiply this by the number of moles.

    32.07 x (5.1 x 10^22) = 163.557 x 10^22 = 1.64 x !0^24

    (Just the opposite of before, this time you are making the 163.557 smaller (1.63).In order to get it back to where it was, you make the number BIGGER so the power of 10 would be POSITIVE). Since you moved 2 positive decimal points, you add and your power of 10 moves from 10^22 to 10^24

  • continually start up with what’s given, thus the style of atoms of Mn: 6.12 x 10^24 atoms Mn x (a million mol Mn/ 6.02 x 10^23 atoms) x (fifty 4.ninety 4 grams Mn/ a million mol Mn) = 558.5262 grams Mn there are 3 given sig figs, so the remarkable answer might desire to be: 559 grams Mn 6.02 x 10^23 == Avogadro’s selection and there are fifty 4.ninety 4 grams in one mole of Mn

  • To find out how many grams this is, you need to know the Avogardo’s Number. Which you can find here:

  • number of moles 3.09*10^24/6.022*10^23=5.131moles

    1 mole weights 64 g

    5.131*64=328g

  • you got a brain , use it or calculate it with a calculater
