Question

if mass of air at sea level is 1034 g cm-2 , calculate the pressure in pascal

Answer 1

mass = 1034g = 1.034 kg
Force = mg = 1.034×9.81 N = 10.143 N
area = 1 cm² = 1×10⁻⁴ m²

Pressure = F/A = 10.134 / 1×10⁻⁴ N/m² = 1.013×10⁵ N/m² = 1.013×10⁵ Pa

So pressure is 1.013×10⁵ Pascal

Answer 2

Answer:

$1.01332 \times 10 {}^{5}$

Step-by-step explanation:

Pressure is Force acting per unit area.

But weight=mg

Therefore,

Pressure =weight per unit area

$1034 \times 9.8$

$1034 g\times 9.8 \times 1kg \div 1000g \times 10000cm \times 1 pa$

=

$1.01332 \times 10 {}^{5} pa$
