Answer 2

Answer: 4) 10.2

Explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.

$pressure=\frac{Force}{area}$

$Force=mass\times acceleration$

We are given:

Pressure = 1.0 Pascal

mass = x mg = $x\times 10^{-6}kg$    $(1kg=10^6mg)$

Area = $1.0 cm^2=0.0001m^2$

$1.0 pascal=\frac{x\times 10^{-6}kg\times 9.8ms^{-2}}{0.0001m^2}$

$x=10.2$

Thus the value of x is 10.2
