Answer:
2.10x10⁻⁹ moles of Si, 143.7 moles of CCl₄, 3.49x10²⁴ atoms
Explanation:
These is the relation:
NA (6.02x10²³) ⇒ 1 mol of particles (it can be, atoms or molecules)
This are the rule of three:
NA of atoms occupies 1 mol of Si
1.27x10¹⁵ atoms will occupy (1.27x10¹⁵ .1 ) / NA = 2.10x10⁻⁹ moles of Si
NA of molecules are contained in 1 mol of CCl₄
8.65x10²⁵ molecules are contained in (8.65x10²⁵ .1)/ NA = 143.7 moles
1 mol of Ca has NA atoms
5.80 moles of Ca will have (5.80 . NA) = 3.49x10²⁴
There are 1952.31g of nickel can be converted to the carbonyl with 3.55 m³ of CO at 100.7 kPa.
Given data
The reaction can be written as:
Ni+4CO ⟶
V(CO)=3.55
T=50°C=323.5K
p=100700Pa
Now, use the formula:
pV=nR*T
Where, P is pressure, V is volume and T is temperature. n=p∗V / R∗T
n=100700∗3.55 / 8.314∗323.15
It is known that,
n(CO)=133.059mol
n(Ni)=n(CO)/4=33.26mol
Mass can be determined by the formula:
Mole = mass / molar mass
Now, put the value of given data in above formula:
m(Ni)=nAr=33.26mol/58.69g/mol
m(Ni)=1952.31g
