Question

Graph between log(x/m) and is a straight line at an angle 45 with intercept on the y-axis, 0.3010. If an amount of the gas absorbed in gram per gram of the absorbent is 0.1x when pressure is 0.2 atm then the value of x is.

• A. $33g$
• B. $22g$
• C. $35g$
• D. $25g$

Answer 1

The correct option is B $22g$

$\log \frac{x}{m}=\frac{1}{n}\log p+\log k\frac{1}{n}=\tan {45}^o=1p=0.2atm\log k=0.3010\frac{x}{m}=0.1x\log \left(0.1x\right)=0.2+1.99x=21.99g=22g$
