Answer: 60 g/ mole SiO2
Explanation: The mass of Si silicon is 28 and the mass of O oxygen is 16. There are 2 oxygen atoms so we will multiply the mass of oxygen by 2.
Si = 28
O = 16 x 2
= 60 g / mole SiO2
Alkenes such as ethene have at least one double bond in their chains and these join to make a polymer called polyethene but alkanes like ethane have only single bonds
Answer:
C6H24S3
Explanation:
To go from Empirical Formula to Molecular Formula, you have to divide the actual amount (given) by the molar mass of the EF:
192 / 2(12.01)+8(1.01)+(32.06)
= 2.99
= 3
Then you multiply every subscript in the EF by 3, which gives you C6H24S3
