How many pounds of nickel have to be used to create alloy that contains 4.9lb of zinc<\/p>\n\n\n\n<p><strong>Correct Answer:<\/strong><br><strong>1.4 pounds of nickel<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Step-by-Step Explanation:<\/strong><\/p>\n\n\n\n<p>The alloy consists of <strong>nickel, zinc, and copper<\/strong> in the ratio <strong>2:7:9<\/strong>. This means for every <strong>2 parts of nickel<\/strong>, there are <strong>7 parts of zinc<\/strong> and <strong>9 parts of copper<\/strong>.<\/p>\n\n\n\n<p>We are told that the amount of <strong>zinc<\/strong> in the alloy is <strong>4.9 pounds<\/strong>, and we need to find how many pounds of <strong>nickel<\/strong> correspond to that, maintaining the same ratio.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Express the ratio<\/h3>\n\n\n\n<p>Total parts = 2 (nickel) + 7 (zinc) + 9 (copper) = <strong>18 parts<\/strong><\/p>\n\n\n\n<p>The <strong>zinc<\/strong> part is 7, so:<\/p>\n\n\n\n<p><strong>7 parts \u2192 4.9 pounds of zinc<\/strong><\/p>\n\n\n\n<p>We need to find how many pounds correspond to <strong>2 parts of nickel<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Find the weight per part<\/h3>\n\n\n\n<p>If <strong>7 parts = 4.9 pounds<\/strong>, then:<\/p>\n\n\n\n<p><strong>1 part = 4.9 \u00f7 7 = 0.7 pounds<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Find nickel weight<\/h3>\n\n\n\n<p>Nickel is <strong>2 parts<\/strong>, so:<\/p>\n\n\n\n<p><strong>Nickel weight = 2 parts \u00d7 0.7 pounds per part = 1.4 pounds<\/strong><\/p>\n\n\n\n<p>Thus, <strong>1.4 pounds of nickel<\/strong> must be used to create the alloy that contains <strong>4.9 pounds of zinc<\/strong>, following the given ratio.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Explanation<\/h3>\n\n\n\n<p>In alloy problems where elements are mixed in a certain ratio, the actual weights can vary, but the proportion between the elements remains constant. The ratio tells us the relative amounts, not the absolute amounts.<\/p>\n\n\n\n<p>For example, the ratio 2:7:9 means that for every <strong>2 units of nickel<\/strong>, there are <strong>7 units of zinc<\/strong>, and <strong>9 units of copper<\/strong>. If you know the actual amount of one element, you can calculate the others by setting up a proportion.<\/p>\n\n\n\n<p>This ensures the alloy maintains its intended properties, as the proportions of different metals affect strength, durability, corrosion resistance, and other characteristics.<\/p>\n\n\n\n<p>In summary, using <strong>1.4 pounds of nickel<\/strong> maintains the exact ratio with <strong>4.9 pounds of zinc<\/strong>, ensuring the correct composition of the alloy.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-512.jpeg\" alt=\"\" class=\"wp-image-33451\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-512.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-512-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-512-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.
