Answer:
0.193 L
Explanation:
Another way of writing the question would be: What volume of a 7.5 M Sodium Bromide solution would contain 1.45 moles.
To answer that we can use the <em>definition of molarity</em>:
- Molarity = moles / liters
We <u>input the given data</u>:
- 7.5 M = 1.45 moles / liters
And <u>calculate how many liters are required</u>:
- 1.45 mol / 7.5 M = 0.193 L
A) C2H6O1
To find the emperical formula, divide each mole value by the smallest
For carbon, 0.013/0.0065 = 2
For hydrogen, 0.038/0.0065= 6
For oxygen, 0.0065/0.0065= 1
Emperical formula = C2H6O1
The force of gravity acts upon all objects; the Earth and the object attract. There are no springs touching the object; thus, there is no spring force. A taut rope is attached to the bucket; this is the cause of the tension force.
C. low boiling points, since convalent bonds are comprise of two non metal elements, the have relatively low boiling points, since most of them are gases.
