The elements that compose seawater, along with the corresponding percents, are shown in the table. If a sample of seawater contains 55 ml, how many ml of hydrogen are in the sample?
To find out how many milliliters of hydrogen are in a 55 ml seawater sample, we need to use the percentage provided for hydrogen in the seawater composition. Here's a detailed, step-by-step solution:
1. Identify the given data: - The volume of the seawater sample: [tex]\( 55 \)[/tex] ml - The percentage of hydrogen in seawater: [tex]\( 10.824\% \)[/tex]
2. Understand what needs to be calculated: - We need to determine the volume of hydrogen in the 55 ml sample.
3. Set up the equation: - Since the percentage represents the proportion of the sample that is hydrogen, we can set up the equation as: [tex]\[
\text{Hydrogen volume} = \left( \frac{\text{Hydrogen percent}}{100} \right) \times \text{Sample volume}
\][/tex]
4. Substitute the given values into the equation: [tex]\[
\text{Hydrogen volume} = \left( \frac{10.824}{100} \right) \times 55
\][/tex]
