Question

Convert 190 mmHg to a) kilopascals b) atmospheres

Answer 1

Answer:

#a. 25.33 kPa

#b. 0.25 atmospheres

Explanation:

• Pressure may be measured using several units which include pascals, atmospheres, mmHg and kilopascals.
• These units of measuring pressure may be converted from one unit to another using a conversion factor.

For example;

1 kPa = 7.5 mmHg

Thus, in our case,

#a. To convert 190 mmHg to kPa

we divide 190 mmHg by 7.5 mmHg

   = 190 mmHg ÷ 7.5 mmHg

  = 25.33 kPa

Hence, 190 mmHg is equivalent to 25.33 kilopascals

Another conversion factor is;

1 atm = 760 mmHg

Therefore, in our case,

#b. To convert 190 mmHg to atmospheres

we divide 190 mmHg by 760 mmHg

That is; 190 mmHg ÷ 760 mmHg

            = 0.25 atm

Thus, 190 mmHg is equivalent to 0.25 atm
