The pressure of a gas is 467mmHg. What is the pressure in terms of atm, torr, and kPa?

0.61 atm, 467 torr, 62.25 KPa

Explanation: To convert pressure units we will use some conversion factors.

1 atm = 760 mmHg. For torr conversion 1 mmHg = 1 torr, and from mmHg to Pa the conversion factor is 1 mmHg = 133.3 Pa.

467 mmHg ( 1 atm / 760 mmHg) = 0.61 atm

467 mmHg ( 1 torr / 1 mmHg) = 467 torr

467 mmHg ( 133.3 Pa / 1 mmHg ) = 62,251 Pa

Convert Pa to KPa

62,251 Pa ( 1 KPa / 1000 Pa ) = 62.25 KPa

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the answer is c i took the test
