A bicycle pump contains 250 mL of air at a pressure of 102 kPa. If the pump is
CaHeK987 [17]

Considering the Boyle's law, the new volume becomes 1,148,344.444 mL or 1148.34 L.

<h3>Boyle's law</h3>

Boyle's law relates pressure and volume, stating that the volume occupied by a given mass of gas at constant temperature is inversely proportional to pressure. This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

P×V=k

Now it is possible to assume that you have a certain volume of gas V1 which is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and the following is true:

P1×V1=P2×V2

<h3>New volume</h3>

In this case, you know:

  • P1= 102 kPa= 10335.1 atm (being 1 kPa= 101.325 atm)
  • V1= 250 mL
  • P2= 2.25 atm
  • V2= ?

Replacing in the Boyle's law:

10335.1 atm ×250 mL= 2.25 atm×V2

Solving:

(10335.1 atm ×250 mL)÷ 2.25 atm= V2

<u><em>1,148,344.444 mL= 1148.34 L=  V2</em></u>

Finally, the new volume becomes 1,148,344.444 mL or 1148.34 L.

What is the mass of 2.35 x 10^21 moles of sodium
lora16 [44]

Answer:

5.41 x 10²² g

Explanation:

Data Given:

no. of moles of sodium = 2.35 x 10²¹ moles

mass of sodium = ?

Solution:

Formula used

         no. of moles = mass in grams / molar mass

To find mass rearrange the above equation:

   mass in grams = no. of moles x molar mass. . . . . . (1)

  • molar mass of Sodium (Na) = 23 g/mol

Put values in equation 1

          mass in grams = 2.35 x 10²¹ moles x 23 g/mol

          mass in grams =  5.41 x 10²² g

So,

mass of Sodium (Na) =  5.41 x 10²² g
