Explain the question more please hggghhg
Answer:
There are 54.03 grams in 3 moles of H2O
There are 3.2 moles in 519.3 g FeCl3
There are 56.0 g in 2 moles of CO
Explanation:
H2O molar mass: 18.01 g/mol
to calculate the grams: 3 mol H2O * 18.01 g/mol
FeCl3 molar mass: 162.2 g/mol
to calculate moles: 519.3g FeCl3 / 162.2 g/mol
CO molar mass: 28.01 g/mol
to calculate grams: 28.01 g/mol CO * 2 mol CO
Answer:
Option (C) 1.30 moles
Explanation:
The following data were obtained from the question:
Volume (V) = 20L
Temperature (T) = 373K
Pressure (P) = 203 kPa
Gas constant (R) = 8.31 L.kPa/mol.K.
Number of mole (n) =...?
The number of mole of the gas in the container can obtained by applying the ideal gas equation as illustrated below:
PV = nRT
Divide both side by RT
n = PV /RT
n = 203 x 20 / 8.31 x 373
n = 1.30 mole.
Therefore, 1.30 mole of the gas is present in the container.
