To do this, we convert 6.64 \u00d7 10\u207b\u00b2\u2077 to have the same power of ten as 3.95 \u00d7 10\u207b\u00b2\u2075.<\/p>\n\n\n\n<p>We rewrite 6.64 \u00d7 10\u207b\u00b2\u2077 as:<\/p>\n\n\n\n<p>6.64 \u00d7 10\u207b\u00b2\u2077 = 0.0664 \u00d7 10\u207b\u00b2\u2075<\/p>\n\n\n\n<p>Now, we can add:<\/p>\n\n\n\n<p>Total mass = (0.0664 \u00d7 10\u207b\u00b2\u2075) + (3.95 \u00d7 10\u207b\u00b2\u2075)<\/p>\n\n\n\n<p>Total mass = 4.0164 \u00d7 10\u207b\u00b2\u2075 kg<\/p>\n\n\n\n<p>Therefore, the total mass is approximately:<\/p>\n\n\n\n<p><strong>4.02 \u00d7 10\u207b\u00b2\u2075 kg<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>When adding or subtracting numbers in scientific notation, the exponents must be the same. This is because the power of 10 determines the scale of the number, so adding numbers with different exponents requires making the exponents equal. In this case, converting 6.64 \u00d7 10\u207b\u00b2\u2077 to 0.0664 \u00d7 10\u207b\u00b2\u2075 allowed us to easily add the two masses. After the addition, the total mass remains in scientific notation with the same power of ten, which is 10\u207b\u00b2\u2075.<\/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-banner5-197.jpeg\" alt=\"\" class=\"wp-image-46931\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-197.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-197-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-197-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-197-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Mass of helium atom is 6.64 \u00d7 10^-27 kg and mass of atom is 3.95 \u00d7 10^-25 Kg .
