Answer:
0.108mol of Hydrogen
Explanation:
The formula for the compound is: CH3COOH
From the formula of the compound,
There are 2moles of oxygen and 4moles of Hydrogen.
If for every 2moles of oxygen, 4moles of Hydrogen is present.
Then, for 0.054 moles of oxygen = (0.054 x 4)/2 = 0.108mol of Hydrogen is present
Answer:
They are in a periodic table
Answer:
0.93g/mL
Explanation:
Given parameters
Mass of wood = 3.16g
Initial volume of water = 20mL
Volume of water + wood = 23.4mL
Unknown:
Density of the wood = ?
Solution:
Density is the mass per volume of a substance.
It is mathematically expressed as;
Density =
Volume of wood = 23.4mL - 20mL = 3.4mL
So,
Density = = 0.93g/mL
