<h3>Further explanation</h3>
Given
%w/w KCl = 32.7
Required
the mole fraction of KCI
Solution
For 100 g solution : KCl = 32.7 g, H₂O = 67.3 g
mol KCl :
mol H₂O :
total mol of solution = 0.439+3.74=4.179
mol fraction of KCl :
Answer:
i think its CaCO3 + 2HCl → CaCl2 + H2O + CO2
Explanation:
Answer: 6.18 g/L
Explanation:
To calculate the density of gas, we use the equation given by ideal gas equation:
Number of moles (n) can be written as:
where, m = given mass
M = molar mass
where,
which is known as density of the gas
The relation becomes:
.....(1)
We are given:
M = molar mass of = 146.06 g/mol
R = Gas constant =
T = temperature of the gas =
P = pressure of the gas = 1 atm
Putting values in equation 1, we get:
Thus density of sulfur hexafluoride gas at exactly 15°C and exactly 1atm is 6.18g/L
If the hydrate gets too hot it could start splattering and cause a loss of sample.
