Shkiper50 [21]
V_{NaOH}=38,1mL=0,0381L\\
C_{m}=0,265M\\\\
n=C_{m}*V=0,265\frac{mol}{L}*0,0381L\approx0,0101mol

HR    +      NaOH ⇒ NaR + H₂O
1mol   :     1mol

0,0101mol \ \ \ \ \Rightarrow \ \ \  \ 2,1g\\
1mol  \ \ \ \ \ \ \ \ \ \ \Rightarrow \ \ \ m\\\\
m=\frac{1mol*2,1g}{0,0101mol}\approx 207,92g\\\\
M_{HR}=207,92\frac{g}{mol}

The air pressure inside a balloon is 0.78 atm. What is this
Troyanec [42]

Answer:

The pressure in mmHg is 59.

Explanation:

Given data:

Pressure of air inside balloon = 0.78 atm

Pressure in mmHg = ?

Solution:

mmHg:

mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.

Symbol:

"mmHg"

Atmosphere (atm)

atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.

1 atm = 760 mmHg

Inorder to convert the atm into mmHg we will multiply the given atm value with 760.

0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg

59 mmHg or 59
