Answer:
0.625 mol
27.5 g
Explanation:
Given data
- Molar mass (M): 44.01 g/mol
- Temperature (T): 19.0°C + 273.15 = 292.2 K
We can find the moles of dinitrogen monoxide gas using the ideal gas equation.
P × V = n × R × T
n = P × V/R × T
n = 0.500 atm × 30.0 L/0.0821 atm.L/mol.K × 292.2 K
n = 0.625 mol
Then, we can find the mass corresponding to 0.625 moles.
0.625 mol × 44.01 g/mol = 27.5 g
<span>Metal conducts electricity, which makes it useful for electricians. Additionally, certain types of metal such as metal wire are flexible and can be manipulated and bent easily by the electrician. Finally, many types of metal are widely available for purchase in stores at a reasonable cost.</span>
The charges on a droplet can be used to represent the number of electrons carried by this droplet.
In other words:
a droplet having a charge of 1.60 x 10^-19 has 1.60 x 10^-19 electrons while a droplet having a charge of 3.15 x 10^-19 has <span>3.15 x 10^-19 electrons.
From the observations:
The fact that the droplets carried different charges signifies the fact the different droplets carried different numbers of electrons</span>
It protects the Earth from harmful solar radiation’s and it regulates heating that is provided by the sun.
