Answer
The methane sample that contains 24 grams of Carbon would contain about 8 grams of hydrogen.
Explanation
To calculate the grams of hydrogen in a methane sample that contains 24 grams of Carbon (C), we need to understand the molecular structure of methane (CH4). Methane consists of one carbon atom and four hydrogen atoms. The molar mass of carbon (C) is approximately 12 g/mol and the molar mass of hydrogen (H) is approximately 1 g/mol. Since there are four hydrogen atoms in methane, the total molar mass of hydrogen in methane is 4*1=4 g/mol.The ratio of the mass of carbon to the mass of hydrogen in methane is hence 12:4 or 3:1. This means that for every 3 grams of carbon, there is 1 gram of hydrogen.Given that the sample contains 24 grams of carbon, the amount of hydrogen in grams can be calculated using the ratio 3:1. Let's denote the amount of hydrogen as x. We can set up the equation as follows:3/1 = 24/xSolving for x gives us x = 24/3 = 8 grams.
