It is calculated by summing the atomic masses of each element in the molecular formula, multiplied by the number of times each atom appears.<\/p>\n\n\n\n<p>In the compound <strong>Na\u2083PO\u2084 (Sodium Phosphate)<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>There are <strong>three sodium (Na)<\/strong> atoms, each with an atomic mass of 22.99 g\/mol. When multiplied by 3, the sodium portion contributes 68.97 g\/mol.<\/li>\n\n\n\n<li>There is <strong>one phosphorus (P)<\/strong> atom, which contributes 30.97 g\/mol.<\/li>\n\n\n\n<li>There are <strong>four oxygen (O)<\/strong> atoms, each contributing 16.00 g\/mol, for a total of 64.00 g\/mol.<\/li>\n<\/ul>\n\n\n\n<p>Adding these values gives a <strong>total molar mass of 163.94 g\/mol<\/strong>. This means that one mole of sodium phosphate weighs 163.94 grams.<\/p>\n\n\n\n<p>Knowing the molar mass is essential in chemistry for converting between grams and moles during stoichiometric calculations in reactions. For example, if you had 327.88 grams of Na\u2083PO\u2084, you could calculate that you have <strong>2 moles<\/strong> of the substance (327.88 \u00f7 163.94 = 2.00 moles).<\/p>\n\n\n\n<p>Understanding molar mass also helps in determining concentrations in solutions and is foundational in both academic and laboratory chemistry practices.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the molar mass of Na3PO4 The correct answer and explanation is: \u2705 Correct Answer: Molar mass of Na\u2083PO\u2084 (Sodium Phosphate) = 163.94 g\/mol \ud83e\uddea Step-by-Step Calculation: To calculate the molar mass of Na\u2083PO\u2084, you add the molar masses of all atoms in the compound: \ud83d\udd22 Total Molar Mass: Molar&nbsp;Mass&nbsp;of&nbsp;Na\u2083PO\u2084=68.97+30.97+64.00=163.94&nbsp;g\/mol\\text{Molar Mass of Na\u2083PO\u2084} = 68.97 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-21962","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21962","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=21962"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21962\/revisions"}],"predecessor-version":[{"id":21963,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21962\/revisions\/21963"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=21962"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=21962"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=21962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
