Answer:
4g/mol
Explanation:
Firstly, we can get the number of moles of the gas present using the ideal gas equation.
PV = nRT
Here:
P = 886 torr
V = 224ml = 224/1000 = 0.224L
T = 55 degrees celcius= 55+ 273.15 = 328.15K
R = molar gas constant = 62.36 L⋅Torr⋅K−1⋅mol−1
n = PV/RT
n = (886 * 0.224)/(62.36 * 328.15)
n = 0.009698469964 mole
Now to get the molar mass, this is mathematically equal to the mass divided by the number of moles. We have the mass and the number of moles, remaining only the molar mass.
First, we convert the mass to g and that is 38.8/1000 = 0.0388
The molar mass is thus 0.0388/0.009698469964 = 4g/mol
Answer:
I think it might be a closed system
<span>There is approximately 15 degrees of Longitude for each tine zone. 24 x 15 = 360.
Latitude does not affect time, however it does affect what time the Sun will rise & set.

Answer:
The most important information is: financial charges, annual fees, minimum payments and how the balance is calculated.
Explanation:
A Schumer Box is a table where the credit card companies disclose all the terms and conditions necessary to make a contract with them, as well as disclose all fees, charges, balances and elements that make up the credit card.
All information shown on a Schumer Box is important, but the most important is that which deals directly with the customer's money or balance. This information is: financial charges, annual fees, minimum payments and how the balance is calculated.
