29.2 grams of methane (carbon tetrahydride), CH4, is how
Elena-2011 [213]

Answer:

1.83moles

Explanation:

Given parameters:

Mass of methane given  = 29.2g

Unknown:

Number of moles = ?

Solution:

To find the number of moles in this mass of a compound;

     Number of moles  = \frac{mass}{molar mass}  

Molar mass of CH₄   = 12 + 4(1)  = 16g/mol

Now;

    Number of moles  = \frac{29.2}{16}   = 1.83moles

sample of atmospheric gas collected at an industrial site is stored in a 250 mL amber glass bottle that has a pressure of 1.02 a
Nady [450]

Answer:- New pressure is 0.942 atm.

Solution:- The volume of the glass bottle would remain constant here and the pressure will change with the temperature.

Pressure is directly proportional to the kelvin temperature. The equation used here is:

P_1T_2=P_2T_1

Where, T_1 and T_2 are initial and final temperatures, P_1 and P_2 are initial and final pressures.

T_1 = 20.3 + 273.15 = 293.45 K

T_2 = -2.0 + 273.15 = 271.15 K

P_1 = 1.02 atm

T_2  = ?

Let's plug in the values in the equation and solve it for final pressure.

1.02atm(271.15K)=P_2(293.45K)

P_2=\frac{1.02atm*271.15K}{293.45K}

P_2 = 0.942 atm

So, the new pressure of the jar is 0.942 atm.
