A gas exerts a pressure of 0.62 atm. Convert this to kPa and mmHg. Be sure to show your work.

The answer to your question is 0.62 atm = 62.82 kPa = 471.2 mmHg

Explanation:

Data

P = 0.62 atm

P = ? kPa

P = ? mmHg

Process

1.- Look for the conversion factor of atm to kPa and mmHg

 1 atm = 101.325 kPa

1 atm = 760 mmHg

2.- Do the conversions

                  1 atm 101.325 kPa

                  0.62 atm  x

                   x = (0,62 x 101.325) / 1

                  x = 62.82 kPa

                   1 atm 760 mmHg

                   0.62 atm  x

                   x = (0.62 x 760)/1

                   x = 471.2 mmHg                

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
