The pressure atop the world’s highest mountain, mount everest, is usually about 33.6 kpa. convert the pressure to atmospheres. how does the pressure compare with the pressure at sea level?

0.33 atm

The pressure at Mount Everest is less as compared to pressure at seal level.

Explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..

All these units of pressure are inter convertible.

We are given:

Pressure atop the world’s highest mountain, Mount Everest = 33.6 kPa mmHg

Converting this unit of pressure into 'atm' by using conversion factor:

1kPa= 0.0099 atm

Thus the pressure atop the world’s highest mountain, Mount Everest, is 0.33 atm

Standard sea-level pressure is 1 atmosphere.

Thus 0.33 atm at Mount Everest is less than 1 atm at sea level.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
