Answer: A. Cilla Is Correct.
That would be 222.0 mm to 4 sig figs
Answer:
B. 39.1 g.
Explanation:
- It is known that every 1.0 mole of any atom contain Avogadros no. of atoms (6.022 x 10²³).
<em>∴ 6.02 x 10²³ atoms are in 1.0 mol of K.</em>
- We need to calculate the mass of 1.0 mol of K using the relation:
<em>∴ </em>mass of K = no. of moles of K x atomic mass of K = (1.0 mol)(39.1 g/mol) = 39.1 g.
