<span>The main difference between carbon-12 and carbon-14 is the number of neutrons present in each compound. Carbon-12 has six neutrons, while carbon-14 has eight neutrons, explains About.com. The differing number of neutrons is responsible for numerous differences between the two compounds.</span>

A sample of N2O effuses from a container in 47s .

malfutka [58]

Answer:

112.92 s.

Explanation:

Let M₁ be the molar mass of N₂O

Let t₁ be the time taken for N₂O to effuse.

Let M₂ be the molar mass of I₂

Let t₂ be the time taken for I₂ to effuse.

Molar mass (M₁) of N₂O = (14×2) + 16 = 28 + 16 = 44 g/mol

Time (t₁) of effusion of N₂O = 47 s

Molar mass (M₂) of I₂ = 127 × 2 = 254 g/mol

Time (t₂ ) of effusion of I₂ =?

The time take for the same amount of I₂ to effuse can be obtained as follow:

t₂/t₁ = √(M₂/M₁)

t₂/47 = √(254 / 44)

Cross multiply

t₂ = 47 × √(254 / 44)

t₂ = 112.92 s

Therefore, it will take 112.92 s for the same amount of I₂ to effuse.

1.505 times 10^23 Na atoms

Svet_ta [14]

Explanation:

Given:

Number of atoms = 1.505 x 10²³

Let us solve for the number of moles and mass of this atom of sodium.

A mole of a substance is the amount of that substance that contains the avogadro's number of particles.

1 mole of Na = 6.02 x 10²³ atoms

Number of moles of Na = $\frac{1.505 x 10^{23} }{6.02 x 10^{23} }$ = 0.25moles

Mass of Na = number of moles x molar mass

Molar mass of Na = 23g/mole

Mass of Na = 0.25 x 23 = 5.75g
