Weight\u00a0in\u00a0kg=173\u2009lbs2.2\u2009lbs\/kg=78.636\u2009kg\\text{Weight in kg} = \\frac{173 \\, \\text{lbs}}{2.2 \\, \\text{lbs\/kg}} = 78.636 \\, \\text{kg}Weight\u00a0in\u00a0kg=2.2lbs\/kg173lbs\u200b=78.636kg<\/li>\n\n\n\n<li><strong>Calculate the mass of calcium<\/strong>:<br>We are told that 1.4% of the human body is calcium. To find how much calcium is in the 78.636 kg body, we multiply the body mass by 1.4% (or 0.014 in decimal form). Mass\u00a0of\u00a0calcium=78.636\u2009kg\u00d70.014=1.1\u2009kg\\text{Mass of calcium} = 78.636 \\, \\text{kg} \\times 0.014 = 1.1 \\, \\text{kg}Mass\u00a0of\u00a0calcium=78.636kg\u00d70.014=1.1kg<\/li>\n<\/ol>\n\n\n\n<p>Thus, the amount of calcium in a 173-pound man is <strong>1.1 kg<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answer:<\/h3>\n\n\n\n<p><strong>1.1 kg Ca<\/strong><\/p>\n\n\n\n<p>This is a straightforward mass-to-mass conversion using percentage calculations. You first convert the weight from pounds to kilograms and then multiply by the given percentage of calcium in the body.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-248.jpeg\" alt=\"\" class=\"wp-image-47495\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-248.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-248-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-248-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-248-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>If 1.4% of the mass of a human body is calcium, how many kilograms of calcium are there in a 173-pound man?
