Answer 3

A) .3(moles) * 55.85(molar mass) = 16.76 Grams
B) negligible as 1 mol is 602200000000000000000000 atoms
C) same as B
D) 1(mol)*1.0(molar mass) = 1 Gram

Answer 4

A because lead is more toward the bottom of the periodic table therefore it is heavier than all other elements

Answer 5

Ur answer is correct

Answer 6

ok thnx

Answer 7

My Pleasure.
