The mass percentage of hydrogen in 300 g of sucrose is 9.75%
From the question given above, we were told that:
2 g of sucrose contains 6.50% (ie 0.065) hydrogen
Thus, we can obtain the percentage of hydrogen in 300 g of sucrose as follow:
2 g of sucrose contains 0.065 hydrogen.
Therefore,
300 g of sucrose will contain =
= 9.75% of Hydrogen.
Thus, 300 g of sucrose contain 9.75% of Hydrogen.

Answer:
heat flows from the object that has more thermal more energy to the object with less thermal energy
Alkanes represent one family of organic compounds that is composed of carbon and hydrogen.
Alkanes are organic compounds that solely have hydrogen and carbon atoms in single bonds and do not have any additional functional groups. Alkanes can be divided into three groups: cycloalkanes, branched alkanes, and linear straight-chain alkanes.
The general formula for alkanes is CnH2n+2. Alkanes are also saturable hydrocarbons. Cyclic hydrocarbons like cycloalkanes have rings-shaped arrangements of their carbon atoms.
Therefore, Alkanes are an example of an organic chemical family made of carbon and hydrogen.
