Answer:

D. 34.5g

Explanation:

Using the following formula to calculate the mass of 1.5moles of sodium (Na);

Mole = mass/molar mass

Molar mass of Na = 23g/mol

mass = mole × molar mass

Mass of Na = 1.5mol × 23g/mol

Mass of Na = 34.5g

The actual yield of a certain reaction is 44.0 g, while the theoretical yield is 50.0 g. Calculate the percent yield.
Goshia [24]
Percent yield represents to what extent the reaction runs to completion. In this, the theoretical yield is 50 grams (100% completion).

To calculate percent yield, divide the actual by the theoretical. In doing so, the percent yield is 88% (44/50).

For the reaction 2 s (s) + 3 o2 (g) → 2 so3 (g), how much so3 can be produced from 4 g o2 and excess s? 1. 0.25 mol so3 2. 0.13
igor_vitrenko [27]
The balanced equation for the above reaction is as follows;
2S + 3O₂ --> 2SO₃
Stoichiometry of O₂ to SO₃ is 3:2
O₂ is the limiting reactant and S is provided in excess. since O₂ is the limiting reactant, the whole amount is consumed in the reaction and amount of product formed depends on amount of limiting reactant present.
Number of O₂ moles reacted- 4 g / 32 g/mol = 0.125 mol
3 mol of O₂ forms 2 mol of SO₃
therefore when 0.125 mol of O₂ reacts number of SO₃ moles - 2/3 x 0.125 mol
Number of SO₃ moles formed - 0.0833 mol
Answer is 4) 0.08 mol
