- Please help ASAP and include steps (pls no links) Which of the following would contain the largest number of atoms?
1. 1.00 gram of beryllium (Be)
2. 1.00 gram of uranium (U)
3. 1.00 gram of sulfur (S)
4. 1.00 gram of iron (Fe)
5. All contain the same number of atoms

2. 1 gram of Uranium (U)

Explanation:

1.

1 g Be x 1 mol/ 9.012182 g = 0.1109609193 mol Be

0.1109609193 mol Be x 6.0221409e+23/ 1 mol = 6.68x10^22 atoms of Be

2.

1 g U x 1 mol/ 238.0289 g = 4.20117053x10^-03 mol U

4.20117053x10^-03 mol U x 6.0221409e+23/ 1 mol = 2.53x10^21

3.

1 g S x 1 mol/ 32.066 g = 0.03118567954 mol S

0.03118567954 mol S x 6.0221409e+23/ 1 mol = 1.88x10^22

4.

1 g Fe x 1 mol/ 55.847 g = 0.01790606478 mol Fe

0.01790606478 mol Fe x 6.0221409e+23/ 1 mol = 1.078328451x10^22

a:

by the combination of an unlimited number of elements

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
