urgent Steve races to the nearest taco stand at lunchtime and sees that his pedometer recorded his peak speed at 74.1 cm/s. What was Steve's peak speed in kilometers per hour?

0.04446 km/hr

Explanation:

For this question, we will be using the dimensional analysis method. Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique.

Steps:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
