Which compound contains the highest percent by mass of hydrogen

Submitted by Krista S. We will assign your question to a Numerade educator to answer.

Percent composition tells you which types of atoms elements are present in a molecule and their levels. Percent composition can also tell you about the different elements present in an ionic compound as well. Percent composition can be calculated the chemical formula of a compound, or it can be determined experimentally. Here is a video which discusses how to calculate percent composition from experimental data for a reaction of iron and oxygen which produces an iron oxide compound. Video from: Noel Pauller.

Which compound contains the highest percent by mass of hydrogen

What is the percent by mass of hydrogen in the compound? These are the key concepts you need to understand to accurately answer the question. Create a table that describes the three common states of matter in terms of their shape, volume, and compressibility. Two unknown compounds are tested. Compound I contains Compound II contains 2. Are the compounds the same? Explain your answer. Rust Iron and oxygen combine to form iron oxide, or rust. List the reactants and products of this reaction.

We'll assume you're ok with this, but you can opt-out if you wish. These are the key concepts you need to understand to accurately answer the question. What percent of calcium carbonate is oxygen?

Percent composition is very simple. Percent composition tells you by mass what percent of each element is present in a compound. A chemical compound is the combination of two or more elements. If you are studying a chemical compound, you may want to find the percent composition of a certain element within that chemical compound. If you want to know the percent composition of the elements in an compound, follow these steps:. Steps to Solve:. Tips for solving:. These steps are outlined in the figure below. For another example, if you wanted to know the percent composition of hydrochloric acid HCl , first find the molar mass of Hydrogen. Now find the molecular mass of HCl: 1.

Which compound contains the highest percent by mass of hydrogen

Packaged foods that you eat typically have nutritional information provided on the label. The label also gives the masses of various types of compounds that are present in each serving. One serving contains 7 g of protein, 15 g of fat, and 3 g of sugar. By calculating the fraction of protein, fat, or sugar in one serving size of peanut butter and converting to percent values, we can determine the composition of peanut butter on a percent by mass basis. Chemists often need to know what elements are present in a compound and in what percentage. In general, percentages may be found by taking the part, dividing it by the whole and multiplying by The percent-by-mass composition is the percent by mass of each element in a compound.
