A) A mixture of atoms and compounds
Answer:WHAT IS THE ELEMENT NAME?
Answer:
601 gram
Explanation:
1st we should know how may moles are there in 1.34 X 10 25 atoms
# moles of Al = # of atoms / # of Avogadro's num
= 1.34 X 10 25/ 6.12X10 23 =
= 22.26 mol of AL
so mass of AL = moles x m.wt
=22.26 x 26.98 = 600.55 = 601 gram
DONE
The formula that only shows the ratio of one atom to another is called the empirical formula.
