\\ \bull\tt\dashrightarrow 2000m=2km

\\ \bull\tt\dashrightarrow 9000mL=9L

\\ \bull\tt\dashrightarrow 6L=6000mL

\\ \bull\tt\dashrightarrow 6cm=60mm

\\ \bull\tt\dashrightarrow 1000m=1km

\\ \bull\tt\dashrightarrow 50mm=5cm

\\ \bull\tt\dashrightarrow 4L=4000mL

\\ \bull\tt\dashrightarrow 10000g=10kg

\\ \bull\tt\dashrightarrow 10000m=10km

\\ \bull\tt\dashrightarrow 4000g=4kg

\\ \bull\tt\dashrightarrow 9km=9000m

What is the pressure of 1.50 moles of a gas in a 30.0L tank at a temperature of<br> 285K?
julia-pushkina [17]

The pressure of the gas : 1.1685 atm

<h3>Further explanation</h3>

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  

n=moles=1.5

V=volumes = 30 L

T=temperature=285 K

The pressure :

\tt P=\dfrac{nRT}{V}\\\\n=\dfrac{1.5\times 0.082\times 285}{30}\\\\P=1.1685~atm
