Answer:
2.26 meters
Step-by-step explanation:
7.59 meters - 2.21 meters - 3.12 meters = 2.26 meters
Answer:
B,C, and E
Step-by-step explanation:
Rounded off to the nearest full number, it would be 3 rounds but that wouldn't make sense because 3 x 10 is 30 sooooo the answer would be 3.5 meaning you paid 1 fifth the price of 10 rounds.
Answer:
Molar mass = 254.60g/mol
Step-by-step explanation:
Mass = 8.02g
Volume = 812mL = 0.812L
Pressure (P) = 0.967atm
Temperature of the gas = 30°C = (30 + 273.15)K = 303.15K
Molecular weight = ?
To solve this question, we'll have to use ideal gas equation, PV = nRT
P = pressure of the gas
V = volume of the gas
n = number of moles of the gas
R = ideal gas constant = 0.082J/mol.K
T = temperature of the gas
PV = nRT
n = PV / RT
n = (0.967 * 0.812) / (0.082 * 303.15)
n = 0.7852 / 24.8583
n = 0.0315 moles
Number of moles = mass / molarmass
Molarmass = mass / number of moles
Molar mass = 8.02 / 0.0315
Molar mass = 254.60g/mol
The molar mass of the gas is 254.60g/mol
