Rank the following samples in mass from least togreatest . a) 3 x 10 23 S atoms

Question

Rank the following samples in mass from least togreatest.

a) 3 x 1023 S atoms
b) 0.5 mol of Cu atoms
c) 0.5 mol of N atoms
d) 6 x 1023 Na atoms

To answer the question, place a four letter word made up ofthe letters a, b, c and d in the answer box. For example, if youthink that sample a has the least mass, followed by sample b,sample c, and finally sample d, then you would type the "word" abcdin the box. Note that the "word" has no spaces or commas.
1 Rank the following samples in number of atoms from leastto greatest.

Explanation / Answer

Divide each number of atoms by avogadro's number to get thenumber of moles. Look up molar mass of each element inperiodic table. This gives you the mass of one mole. Then, multiply each "molar mass" by the number of moles ofatoms. a. (0.5)(32) = 16 g b. (0.5)(63.5) = 31.75 g c. (0.5)(14) = 7 g d (1.0)(23) = 23 g _ Find the number of moles (divide mass by molar mass) and thenmultiply by avogadro's number. a. (1.5)(6.022E23) = 9.033 E 23 atoms b. (64)(6.022E23)/14 = 2.75 E 24 atoms c. (20)(6.022E23)/9 = 1.34 E 24 atoms d. (25)(6.022E23)/23 = 6.54 E 23 atoms _ Part 3 is the same as Part 1
