Explanation:
Moles of Oxygen = 64/16 = 4
Moles of Hydrogen = 8/1 = 8
Hence the empirical formula is H2O.
Answer:
The new volume will be 5.80 L
Explanation:
Step 1: Data given
The initial volume = 29.0 L
The initial pressure = 562 torr = 562 /760 atm = 0.739474 atm
The pressure changes to 2810 torr = 2810 /760 atm = 3.697368 atm
The temperature and number of moles will not change
Step 2: Calculate the new volume
P1*V1 = P2*V2
⇒With P1 = the initial pressure = 0.739474 atm
⇒with V1 = the initial volume = 29.0 L
⇒with P2 = the increased pressure = 3.697368 atm
⇒with V2 = The new volume = TO BE DETERMINED
0.739474 atm * 29.0 L = 3.697368 atm * V2
V2 = 5.80 L
OR
562 torr * 29.0 L = 2810 torr * V2
V2 = 5.80 L
The new volume will be 5.80 L

Answer:
1.69 g Na₂O
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.0273 mol Na₂O
<u>Step 2: Identify Conversions</u>
Molar Mass of Na - 22.99 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Na₂O - 2(22.99) + 16.00 = 61.98 g/mol
<u>Step 3: Convert</u>
<u />
= 1.69205 g Na₂O
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
1.69205 g Na₂O ≈ 1.69 g Na₂O
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. F = ma; a = F/m. This means that Force over the mass. In order to improve the acceleration without redesigning is that the company has to improve the force assuming that the mass is still the same.
