Answer:</h3>
2.047 × 10^24 atoms
<h3>
Explanation:</h3>
- We need to know that 1 mole of an element contains atoms equivalent to the Avogadro's constant.
- The Avogadro's constant is 6.022 × 10^23.
- Therefore, 1 mole of Fe contains 6.022 × 10^23 atoms.
In this case we are given 3.4 moles of Iron.
we are required to find the number of atoms in 3.4 moles.
Therefore, since 1 mole of Fe contains 6.022 × 10^23 atoms.
Then, 3.4 mole will contain;
= 3.4 moles × 6.022 × 10^23 atoms/mole
= 2.047 × 10^24 atoms
Thus, 3.4 moles of Iron contains 2.047 × 10^24 atoms
Answer:
Physical properties
Explanation:
These properties are the ones that you can observe or collect by your senses, for example the color, the odor, the sound, the texture, etc. In this case the substance is not going to change to a new one, it could be that is changing of state.
ANSWER:
2.65 g H2O
Explanation:
6.49g (co2) / 44.009g (co2) x 1 mol (co2) / 1 mol (h2o) x 1 mol (h2o)
=0.147 mol H2O
0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)
=2.65 g H2O
