What would be the formula for an alkane which contains 30 hydrogen atoms? C__H30 16 18 14 15
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
A hydrocarbon that contains only carbon and hydrogen atoms attached through single bonds is known as an alkane.
General formula for alkanes is where n is any integer.
For example, a hydrocarbon with 30 hydrogen atoms will have the value of "n" as follows.
Total hydrogen atoms = 2n + 2
30 = 2n + 2
30 - 2 = 2n
n = 14
Therefore, number of carbon atoms in this hydrocarbon will be 14.
Hence, we can conclude that formula for an alkane which contains 30 hydrogen atoms is .

Answer:
40.03g/mole
Explanation:
Given parameters:
Mass = 42.10 g/mole and abundance = 93.50%
Mass = 8.30 g/mole and abundance = 6.200%
Mass = 50.40 g/mole and abundace = 0.3000%
Find;
Average atomic mass = ?
Solution:
Average atomic mass = sum (mass x abundance)
Average atomic mass = () + (
x 8.3) + (
)
= 39.36g/mole + 0.52g/mole + 0.15g/mole
= 40.03g/mole
Answer:
The salt is barium chloride.
Explanation:
Moles of barium sulfate =
According to reaction, 1 mol of barium sulfate is produced from 1 mol of .
Then 0.0480 moles will be produced from:
of
.
Mass of used = 10.00 g
Moles of =\frac{10.00 g}{\text{Molar mass}}[/tex]
Molar mass of = 208.33 g/mol
The nearest answer to our answer is .
The correct answer barium chloride with molar mass of 208.2 g/mol.
