Suppose that 0.00150 moles of CO2 (44.0 g/mol) effuse out of a pinhole in 1.00 hour. How many moles of N2 (28.0 g/mol) would eff

use out of the same pinhole in 1.00 hour? Assume both gases are at the same temperature and pressure.

Answer:

0.0019mol

Explanation:

To solve this problem, first we calculate for the rates of the effusion:

For CO2,

Number of mole = 0.00150 mol

Time = 1h

R1 = mol / time

R1 = 0.0015/1

R1 = 0.0015mol/h

Molar Mass of CO2 (M1) = 44.0 g/mol

For N2,

R2 =?

Molar Mass of N2 (M2) = 28.0 g/mol

Using Graham's law, we can obtain Rate (R2) of N2 as follows:

R1/R2 = √(M2/M1)

0.0015/R2 = √(28/44)

0.0015/R2 = 0.7977

R2 = 0.0015 /0.7977

R2 = 0.0019mol/h

But rate = mole /time

Time = 1h

Rate od N2 = 0.0019mol/h

0.0019 = mole /1

Mole = 0.0019mol

Therefore, the number of mole of N2 is 0.0019mol

Two unknown compounds are analyzed. Compound I contain 5.63 g of tin and 3.37 g of chlorine, while compound II contains 2.5 g of
never [62]

Answer:

Compounds 1 and 2 are not the same

Explanation:

To solve this question we need to find the molecular formula of the compounds converting the mass of each atom to moles. Molecular formula is defined as the simplest whole number ratio of atoms present in a molecula:

Compound 1:

<em>Moles Tin: </em>

5.63g Sn * (1mol / 118.7g) = 0.04743 moles

<em>Moles Cl:</em>

3.37g Cl * (1mol / 35.45g) = 0.09506 moles

Ratio Cl:Sn

0.09506 moles / 0.04743 moles = 2

Molecular formula SnCl₂

Compound 2:

<em>Moles Tin: </em>

2.5g Sn * (1mol / 118.7g) = 0.02106 moles

<em>Moles Cl:</em>

2.98g Cl * (1mol / 35.45g) = 0.08406 moles

Ratio Cl:Sn

0.08406 moles / 0.02106 moles = 4

Molecular formula SnCl₄

Compounds 1 and 2 are not the same because molecular formulas are different.
