How many atoms of zinc are in 6.05 moles of zinc

stiv31 [10]

As we know that one mole contains 6.022 × 10²³ particles. And the number of particles are related to moles as,

# of Particles = Moles × 6.022 × 10²³ particles

In case of Zinc atoms,

# of Atoms = Moles × 6.022 × 10²³ Atoms/mol

Putting value of moles.

# of Atoms = 6.05 mol × 6.022 × 10²³ Atoms/mol

# of Atoms = 3.64 × 10²⁴ Atoms

How many moles of gas occupy 98 l at a pressure of 2.8 atmospheres and a temperature of 292 k?

Furkat [3]

From the ideal gas equation, we know that PV = nRT
where, P = pressure, V = volume occupied, n = number of moles of gas, R = universal gas constant=0.082L atm mol-1 K-1 and T = temperature.
Given: P = 2.8 atm, V = 98 l and T = 292 k.
Therefore n = $\frac{PV}{RT}$ = $\frac{2.8 X 98}{0.082 X 292}$ = 11.46
