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
