Answer:
Mole = 2.67
Given data:
Number of atoms of carbon = 1.61 × 10²⁴
Avogadro's Number = 6.023 × 10²³
Required:
Moles = ?
Solution:
Formula for calculating moles from particle numbers is given as,
Mole = Number of particle / Avogadro's number
putting values
Moles = 1.61 × 10²⁴ / 6.023 × 10²³
Moles = 2.67

I think the answer is False.
Answer:
This equation is balanced.
Explanation:
To determine whether an equation is balanced or not, we must make sure that there are the same number of each type of atoms in both the reactants (on the left side of the equation) and the products (on the right side of the equation).
We can see that there are two atoms of nitrogen on the left side of the equation. When we look at the right side of the equation, we see that there are two molecules of NH6, with one atom of nitrogen each. Since 2 * 1 = 2, there are two atoms of nitrogen in the products as well. This means that the nitrogen atoms are balanced.
Next, we must look at the hydrogen atoms. There are 6 molecules of H2, which contains 2 atoms of hydrogen each. Since 6 * 2 = 12, there are 12 atoms of hydrogen in the reactants. On the right side of the equation, there are 2 molecules of NH6, which contains 6 atoms of hydrogen each. Since 2 * 6 = 12, there are 12 atoms of hydrogen in the products as well. Since there are 12 atoms on both sides of the equation, the hydrogen atoms are balanced.
Since both types of atoms that are presented in this equation are balanced, we can conclude that the overall equation is balanced.
Hope this helps!
From ideal gas equation that is PV=nRT
n(number of moles)=PV/RT
P=760 torr
V=4.50L
R(gas constant =62.363667torr/l/mol
T=273 +273=298k
n is therefore (760torr x4.50L) /62.36367 torr/L/mol x298k =0.184moles
the molar mass of NO2 is 46 therefore density= 0.184 x 46=8.464g/l
