Answer:
![\boxed{\text{2.2 g/L}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B2.2%20g%2FL%7D%7D)
Explanation:
We can use the Ideal Gas Law to calculate the density of the gas.
pV = nRT
n = m/M Substitute for n
pV = (m/M)RT Multiply both sides by M
pVM = mRT Divide both sides by V
pM = (m/V) RT
ρ = m/V Substitute for m/V
pM = ρRT Divide each side by RT
![\rho = \frac{pM }{RT}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7BpM%20%7D%7BRT%7D)
Data:
p = 1.00 bar
M = 49 g/mol
R = 0.083 14 bar·L·K⁻¹mol⁻¹
T = 0 °C = 273.15 K
Calculation:
ρ = (1.00 × 49)/(0.083 14 × 273.15) = 2.2 g/L
The density of the gas is
.
Answer:
The current of the toaster is 3.93A
Explanation:
Using the GRASS method:
G: Given: The information that is given is that we have 28Ω of Resistance and 110V of voltage.
R: Required: We need to find the current measured.
A: Action: We can use Ohm's law that relates resistance, voltage and current in the equation:
V = R*I
Or:
I = V/R
<em>Where I is current in A, V is voltage = 110V and R is resistance = 28Ω</em>
S: Solve:
I = 110V / 28Ω
I = 3.93A
S: Statement:
<h3>The current of the toaster is 3.93A</h3>
