One electron has a charge of -1.6* 10^-19 c

x electrons have a charge of -0.90 c


1/x = -1.6 * 10^-19 c / - 0.9 c cancel the c's. and the - signs.


1/x = 1.6 * 10^-19 / 0.9 Cross multiply

0.9 = 1.6 * 10^-19 x Divide by 1.6 * 10^-19

0.9 / 1.6 * 10^-19 = x

x = 5.625 * 10^18 electrons.

The pressure in car tires is often measured in pounds per square inch ( lb/in.2 ), with the recommended pressure being in the ra
Goshia [24]

when we convert 32.5 lb/in² to atmosphere, the result obtained is 2.21 atm

<h3>Conversion scale</h3>

14.6959 lb/in² = 1 atm

<h3>Data obtained from the question</h3>
  • Pressure (in lb/in²) = 32.5 lb/in²
  • Pressure (in ATM) =?

<h3>How to convert 32.5 lb/in² to atm</h3>

14.6959 lb/in² = 1 atm

Therefore

32.5 lb/in² = 32.5 / 14.6959

32.5 lb/in² = 2.21 atm

Thus, 32.5 lb/in² is equivalent to 2.21 atm
