A 75.0-milliliter lightbulb is filled with neon. There are 7.16 × 10-4 moles of gas in it, and the absolute pressure is 116.8 ki
Fantom [35]

Answer:- 1467 K

Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.

Given: n=7.16*10^-^4moles

V = 75.0 mL = 0.0750 L

P = 116.8 kPa

We know that, 101.325 kPa = 1 atm

So, 116.8kPa(\frac{1aym}{101.325kPa})

= 1.15 atm

R is universal gas constant and it's value is 0.0821\frac{atm.L}{mol.K} .

T = ?

Let's plug in the values in the equation and solve it for T.

1.15(0.0750)=7.16*10^-^4*0.0821(T)

0.08625 = 0.00005878(T)

T=\frac{0.08625}{0.00005878}

T = 1467 K

So, the temperature of the light bulb would be 1467 K.
