Answer:
53.29% of acetic acid is Oxygen
Explanation:
Step 1: Given data
Acetic acid it's molecular formula is HC2H3O2. This means it consists of 3 elements Carbon, Hydrogen and oxygen.
Step 2: the molar masses
The molecular mass of acetic acid is:
4* H = 4* 1.01 g/mole
2* C = 2*12 g/mole
2*O = 2* 16 g/mole
Total molar mass = 4+ 24+32 = 60.052 g/mole
Step 3: Calculate the mass percent
32 g of the 60.052 g is Oxygen
(32/60.052) *100% = 53.29%
53.29% of acetic acid is Oxygen.
Answer:
0.0001637 mol
Explanation:
PV = nRT
Very important formula in chem
2.3 atm * 0.0017 L = n * 0.082057 * 291 K
= 0.0001637 mol O2
This concept is very important in chem, practice it.
Answer:
27.4 g/mol
Explanation:
Assuming the compound is a gas and that it behaves ideally, we can solve this problem by using the <em>PV=nRT formula</em>, where:
- V = 245 mL ⇒ 245 mL / 1000 = 0.245 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
<u>Inputting the data</u>:
- 1.22 atm * 0.245 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
<u>Solving for n</u>:
With the <em>calculated number of moles and given mass</em>, we <u>calculate the molar mass</u>:
- 0.334 g / 0.0122 mol = 27.4 g/mol
