Answer:
The final volume of the bubble is 7.13 mL.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 3 atm
= final pressure of gas = 0.95 atm
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:

The final volume of the bubble is 7.13 mL.
Answer:
i hope my answer help u :))
Explanation:
no , it will be 39.99711
Molar mass NaCl = 58.44 g/mol
number of moles:
mass NaCl / molar mass
145 / 58.44 => 2.4811 moles of NaCl
Volume = 3.45 L
Therefore :
M = moles / volume in liters:
M = 2.4811 / 3.45
M = 0.719 mol/L⁻¹
hope this helps!
