Answer:
Option (2)
Explanation:
The two compounds formed will be AgCl and NaNO₃.
We can see that this will result in a balanced equation, so the answer is Option (2).
mass = mol no. x molar mass
= 13.6 x 56+(3x14)+(9x16)
= 242g
Answer:
1326.6 × 10⁻²³g
Explanation:
Given data:
Number of atoms of iron = 143 atoms
Average atomic mass of iron = 55.845 amu
Mass of iron = ?
Solution:
It is known that,
55.845 g of iron = one mole of iron = 6.02× 10²³ atoms
For 143 atoms:
143 atoms /6.02× 10²³ atoms × 55.845 g
23.754 × 10⁻²³× 55.845 g
1326.6 × 10⁻²³g
