Answer:

F=ma. Force is equal to mass times acceleration. The accleration of an object depends on the net force.

Explanation:

I know its F=ma but I think this is right I hope it helps

A 17.4 L sample of oxygen gas (O2) was collected at a temperature of 23.0°C and a pressure of 2.18 atmospheres. What volume woul

timofeeve [1]

The volume of the gas at STP = 35.01 L

<h3>Further explanation</h3>

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).

In general, the gas equation can be written

$\large {\boxed {\bold {PV = nRT}}}$

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.08206 L.atm / mol K

T = temperature, Kelvin

V=17.4 L

T = 23 + 273 = 296 K

P = 2.18 atm

$\tt mol=n=\dfrac{PV}{RT}\\\\n=\dfrac{2.18\times 17.4}{0.082\times 296}\\\\n=1.563$

The volume of the gas occupy at STP :

$\tt 1.563\times 22.4=35.01~L$
