Answer:
194.6 mL of SO₂
Explanation:
The reaction that takes place is:
P₄S₃ + 6O₂(g) → P₄O₁₀ + 3SO₂(g)
<u>To solve this problem we need to use PV=nRT</u>, so first let's convert the given units:
- 23.8 °C → 23.8 + 273.15 = 296.95 K
- 747 torr → 747/760 = 0.983 atm
We need to calculate V, so in order to do that we calculate n, using the mass of the reactant (P₄S₃):
0.576 g P₄S₃ *
= 7.85 * 10⁻³ mol SO₂ = n
PV=nRT
0.983 atm * V = 7.85 * 10⁻³ mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 296.95 K
V = 0.1946 L
- Finally we convert L into mL:
0.1946 * 1000 = 194.6 mL
Atomic mass is the answer!!
Explanation: An elements atomic number won’t be able to change
It is two or more objects and different things that can be removed from each other.
Answer:
<h3>The answer is 1.63 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual mass = 9.80 g
error = 9.80 - 9.64 = 0.16
We have

We have the final answer as
<h3>1.63 %</h3>
