Answer:
Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.
9.587 cm^3
Explanation:
The balanced equation for the chemical reaction is shown below:
⇒
In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:
Using STP, 1 mole of gas has a volume of 22.4 L
Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4
since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles
we can convert the moles to L by multiplying with 22.4
volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3
Answer:
Approximately 53.3 %.
Explanation:
Molar mass of C2H4O2
= 2 * 12.011 + 4 * 1.008 + 2 * 15.999
= 60.052
% oxygen = (31.998* 100) / 60.052 = 53.28 %
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
