Atmosphere pressure is about 100000 Pa. Calculate the force of the Atmosphere on a person whose Surface area is 2.0m
Sedaia [141]

Answer:

The force of the atmosphere 200 KN.

Explanation:

Pressure is the ratio of force applied to the area  to which the force is applied.

i.e Pressure = \frac{Force}{Area}

But, Pressure = 100000 pa (100000 N/ m^{2}), and surface area = 2.0 m^{2}

Thus,

100000 = \frac{Force}{2.0}

⇒ Force = 100000 x 2.0

              = 200000

Force = 200 KN

The force of the atmosphere 200 KN.

A 0.500 g sample of tin (Sn) is reacted with oxygen to give 0.534 g of product. What is the percent mass of the tin and percent
AleksAgata [21]

Answer:

Percentage mass of Tin = 96.3%

Percentage mass of oxygen = 6.40%

Explanation:

The product of the reaction is an oxide of tin.

Assuming all of the 0.500 g sample of tin reacted with oxygen to produce the oxide:

Mass of oxide = 0.534 g

Mass of tin present in the oxide = 0.500 g

Mass of oxygen in the oxide = 0.534 g of oxide - 0.500 g Sn = 0.034 g O

Percentage composition = mass of element/mass of compound × 100%

Percentage composition of Sn = 0.500 g/0.534 g × 100 = 93.6% Sn

Percentage composition of oxygen = 0.034 g/0.534 g × 100 = 6.40%
