Example Input: Context: A solution is a mixture of two or more substances in which dissolved particles are distributed evenly throughout the solution. The substance that dissolves in a solution is called the solute, and the substance that does the dissolving is called the solvent. The concentration of a solution is the amount of solute in a given amount of solution. A solution with a lot of dissolved solute has a high concentration and is called a concentrated solution. A solution with little dissolved solute has a low concentration and is called a dilute solution. The concentration of a solution represents the percentage of the solution that is the solute. You can calculate the concentration of a solution using this formula: Concentration = Mass (or volume) of Solute Mass (or volume) of Solution 100% For example, if a 100-gram solution of salt water contains 3 grams of salt, then its concentration is: Concentration = 3g 100g 100% = 3% Q: A 1000 mL container of brand A juice drink contains 250 mL of juice and 750 mL of water. A 600 mL container of brand B juice drink contains 200 mL of juice and 400 mL of water. Which brand of juice drink is more concentrated, brand A or brand B? 250 mL 1000 mL 100% = 25% 200 mL 600 mL 100% = 33% A: Concentration(A) = Concentration(B) = You can conclude that brand B is more concentrated.
Question: a solution with a small amount of solute for a given amount of solution is called
Example Output: dilute.

Example Input: Context: People depend on natural resources for just about everything that keeps us fed and sheltered, as well as for the things that keep us entertained. Every person in the United States uses about 20,000 kilograms (40,000 pounds) of minerals every year for a wide range of products, such as cell phones, TVs, jewelry, and cars. Table 1.1 shows some common objects, the materials they are made from, and whether they are renewable or non-renewable. Common Object Natural Resources Used Cars 15 different metals, such as iron, lead, and chromium to make the body. Precious metals like gold, silver, and platinum. Gems like diamonds, rubies, emer- alds, turquoise. Jewelry Are These Resources Renewable or Non-Renewable? Non-renewable Non-renewable Common Object Natural Resources Used Electronic Appliances (TVs, com- puters, DVD players, cell phones, etc.) Clothing Many different metals, like copper, mercury, gold. Food Bottled Water Gasoline Household Electricity Paper Houses Soil to grow fibers such as cotton. Sunlight for the plants to grow. Animals for fur and leather. Soil to grow plants. Wildlife and agricultural animals. Water from streams or springs. Petroleum products to make plastic bottles. Petroleum drilled from wells. Coal, natural gas, solar power, wind power, hydroelectric power. Trees; Sunlight Soil. Trees for timber. Rocks and minerals for construc- tion materials, for example, granite, gravel, sand. Are These Resources Renewable or Non-Renewable?
