I just started learning about kinetic molecular theory, and I’m not sure how to answer the question circled below

lions [1.4K]

Answer : The value of 'R' is $0.0821\text{ L atm }mol^{-1}K^{-1}$

Solution : Given,

At STP conditions,

Pressure = 1 atm

Temperature = 273 K

Number of moles = 1 mole

Volume = 22.4 L

Formula used : $R=\frac{PV}{nT}$

where,

R = Gas constant

P = pressure of gas

T = temperature of gas

V = volume of gas

n = number of moles of gas

Now put all the given values in this formula, we get the values of 'R'.

$R=\frac{(1atm)\times (22.4L)}{(1mole)\times (273K)}$

$R=0.0821\text{ L atm }mol^{-1}K^{-1}$

Therefore, the value of 'R' is $0.0821\text{ L atm }mol^{-1}K^{-1}$ .

A power drill runs at a voltage of 120 V and draws a current of 4 A. What is the wattage of the drill?

creativ13 [48]

First this is not Chemistry..

And to answer this you need to know simple formula :)

Wattage = Voltage * Ampere

So the answer is 480 Wattage
