A boy with pneumonia has lungs with a volume of 1.7 L that fill with 0.070 mol of air when he inhales. When he exhales, his lung
BlackZzzverrR [31]

Answer:

0.053moles

Explanation:

Hello,

To calculate the number of moles of gas remaining in his after he exhale, we'll have to use Avogadro's law which states that the volume of a given mass of gas is directly proportional to its number of moles provided that temperature and pressure are kept constant. Mathematically,

V = kN, k = V / N

V1 / N1 = V2 / N2= V3 / N3 = Vx / Nx

V1 = 1.7L

N1 = 0.070mol

V2 = 1.3L

N2 = ?

From the above equation,

V1 / N1 = V2 / N2

Make N2 the subject of formula

N2 = (N1 × V2) / V1

N2 = (0.07 × 1.3) / 1.7

N2 = 0.053mol

The number of moles of gas in his lungs when he exhale is 0.053 moles

How does the tendency of iron to rust depend on ph?
mojhsa [17]
The  tendency  of  iron  to  rust   depend  on  the  Ph   of solution

 The   formation  of  rust  increases  as  the  PH  decreases.  This  led  agent  of  rusting  that  is  oxygen  gets  more  positive  as  H+  ions  increase   which  facilitate     rusting. The    lower  the  Ph  level  the   quick  the   corrosion.
