Salutations!
A large gently sloping volcano with a fluid eruption is called shield volcano. The fluid is basaltic lava and the slops are gently sliding.
Hope I helped (:
Have a great day!
Answer:
The water of crystallization of the intermediate analyte is 5.
Seeing as the question does not provide the value for weight of the salt on further heating (at 120° C), you can apply the steps in this explanation to attain that value.
Explanation:
XSO4.7H2O → XSO4 + 7H2O
8.1g 4.9g
8.1 - 4.9 = 3.9g of water evaporated
The ration of water to salt is:
XSO4 : H2O
grams : 4.9 3.2
moles: 72 + 32 + (16×2)=136 (1×2)+ 16= 18
0.036 0.178 (divide both sides by smallest value)
1 4.93
∴ <u>water of crystallization of intermediate is 5.</u>
Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
<h3>How can molar mass of a gas be obtained from density, temperature and pressure?</h3>
The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
- molar mass = density × molar gas constant × temperature/pressure
Molar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu
Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
