Answer:
SO3
Explanation:
Data obtained from the question include:
S = 40%
O = 59%
To obtain the empirical formula, do the following:
Divide the above by their molar mass as shown below:
S = 40/32 = 1.25
O = 59/16 = 3.69
Next, divide by the smallest as shown below:
S = 1.25/125 = 1
O = 3.69/1.25 = 3
Therefore, the empirical formula is SO3

Answer:
78.12g of acetylene
Explanation:
Acetylene and calcium hydroxide are produced when H₂O reacts with CaC₂. The reaction is:
2 H₂O + CaC₂ → C₂H₂ + Ca(OH)₂
<em>Where 1 mole of C₂H₂ (acetylene) is produced per mole of CaC₂</em>
Thus, the addition of 3 moles of CaC₂ produces 3 moles of acetylene.
As molecular mass of acetylene is 26.04g/mol, grams of acetylene produced are:
3mol C₂H₂ × (26.04g / mol) = <em>78.12g of acetylene</em>
Answer:
.562 mol (with respect to signifigant figures)
Explanation:
to find moles we must use concentration to cancel liters.
2.250 mol/L x .250 L = .5625 mol
