Oc. 9.90
O d. 525

Answer 1

the answer is 70.0kPa

Answer 2

A. 70.0 kpa

Step-by-step explanation:

Given

Pressure = 525.4 torr

Required

Convert to kPa

From standard unit of conversion;

`1\ torr = 0.133\ kPa`

Multiply both sides by 525.4

`525.4 * 1\ torr = 525.4 * 0.133\ kpa`

`525.4\ torr = 70.047572\ kpa`

`525.4\ torr = 70.0\ kpa` (Approximated)

From the list of given options, option A is the closest answer after 525.4 torr is converted to its kpa equivalent
