The highest sustained pressure achieved in the laboratory is 1.5 × 107 kilopascals, kpa. what is this pressure in atm, mmhg, and torr?

1.5 × 10⁷ kPa = 148038.5 atm = 1.12 x 10⁸ mmHg = 1.12 x 10⁸ torr.

Explanation:

Knowing that:

1 atm = 101.325 kPa.

??? atm = 1.5 × 10⁷ kPa.

Using cross multiplication:

∴ 1.5 × 10⁷ kPa = (1 atm)(1.5 × 10⁷ kPa)/(101.325 kPa) = 148038.5 atm,

Knowing that:

1.0 kPa = 7.5 mmHg.

1.5 × 10⁷ kPa = ??? mmHg.

Using cross multiplication:

∴ 1.5 × 10⁷ kPa = (7.5 mmHg)(1.5 × 10⁷ kPa)/(1.0 kPa) = 1.12 x 10⁸ mmHg.

Knowing that:

1.0 kPa = 7.5 torr.

1.5 × 10⁷ kPa = ??? torr.

Using cross multiplication:

∴ 1.5 × 10⁷ kPa = (7.5 torr)(1.5 × 10⁷ kPa)/(1.0 kPa) = 1.12 x 10⁸ torr.

the answer is true.
