Iron, magnesium, zinc, aluminum. I don’t know of any others
no. moles = the weight / molecular mass
for our cas the molecular mass will be = with the atomic mass
=>
no moles = 0,4
atomic mass = 197 u.a.m.
=> mass of gold = 0,4 * 197 = 78,8 grs.
Answer:
1 unit
Explanation:
It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units.
1/12 * 12 = 1. I think so.
If it is assumed that there are only two isotopes then the percent abundance needs to add up to 100%
100-35= 65%
The second isotope will have a 65% abundance.

Explanation:
Solids have definite shape and distinct boundaries as such the intermolecular forces between them is maximum
