Once the water has been added, the mass of the water is calculated to be
(Mass of flask + water) - mass of the flask
mass water = 95.023 - 85.135 = 9.888
Density = mass / volume
Density = 9.888 / 10 = 0.9888
% error = [(what it should be - what it is)/(what it should be)] * 100
% error = (0.9992 - 0.9888) / 0.9992 * 100 = 0.04003 % error.
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
I think 1 is b 2 is d 3 is a 4 is d 5 is b 6 is c and 7 is b I hope my awnsers helped .
