Answer:
<h2>11.93 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>11.93 moles</h3>
Hope this helps you
#1
- Nephilim has very weak intermolecular forces
- So on heating it directly turns gas from solid.
#2
- Nathaline is non polar
- Water is polar
So it is not expected to dissolve in water.
#3
Empirical formula mass
n:-
- Molecular formula mass/Empirical formula mass
- 128/64
- 2
Molecular formula
- n×Empirical formula
- 2(C_5H_4)
- C_10H_8
2 protons+, 1 neutron, and 2electrons-
Answer:
1) 7.256 mol Br2 (Cl2)/(Br2)
The Br2 cancels out, so we have 7.256(2)
This is 14.512.
2) Number of moles = mass / molar mass
Number of moles = 239.7 g/ 35.5 g/mol
Number of moles = 6.8 mol
BrCl=13.6 mol
13.6(11.5.357)
1568.9 g
3) Repeat the same process with problem 2, given that there are 6.022x10^23 atoms in a mole.
Explanation:
Br2 + Cl2 → 2BrCl
