Answer:
16 g/mol
Explanation:
In CO2, it means we have 1 mole of carbon and 2 moles of oxygen.
However, we want to find the molar mass of just a single mole of oxygen.
Now, from tables of values of elements in electronic configuration, the molar mass of oxygen is usually approximately 16 g/mol.
In essence the molar mass is simply the atomic mass in g/mol
Answer:
Red, because it has less volume and more amount of matter.
Explanation:
Sliding or rolling friction
Neither of them are used in magnets they don’t attract metal
Answer:
The answer is
<h2>13.84 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 22.4 L
error = 22.4 - 19.3 = 3.1
The percentage error is
We have the final answer as
<h3>13.84 %</h3>
