Therefore, each molecule of PF\u2083 contains:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 phosphorus atom<\/li>\n\n\n\n<li>3 fluorine atoms<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Find the Number of Molecules in 1.4 millimoles<\/h3>\n\n\n\n<p>Since 1 mole of any substance contains Avogadro\u2019s number of particles (6.022 \u00d7 10\u00b2\u00b3), we need to calculate the number of molecules in 1.4 millimoles of PF\u2083. First, convert millimoles to moles: 1.4\u2009mil=1.4\u00d710\u22123\u2009mol1.4 \\, \\text{mil} = 1.4 \\times 10^{-3} \\, \\text{mol}<\/p>\n\n\n\n<p>Now, calculate the number of molecules in 1.4 millimoles: 1.4\u00d710\u22123\u2009mol\u00d7(6.022\u00d71023\u2009molecules\/mol)=8.428\u00d71020\u2009molecules1.4 \\times 10^{-3} \\, \\text{mol} \\times (6.022 \\times 10^{23} \\, \\text{molecules\/mol}) = 8.428 \\times 10^{20} \\, \\text{molecules}<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Calculate the Total Number of Atoms<\/h3>\n\n\n\n<p>Since each molecule of PF\u2083 contains 1 phosphorus atom and 3 fluorine atoms, there are 4 atoms per molecule of PF\u2083. Therefore, to find the total number of atoms, multiply the number of molecules by the number of atoms per molecule: 8.428\u00d71020\u2009molecules\u00d74\u2009atoms\/molecule=3.371\u00d71021\u2009atoms8.428 \\times 10^{20} \\, \\text{molecules} \\times 4 \\, \\text{atoms\/molecule} = 3.371 \\times 10^{21} \\, \\text{atoms}<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answer:<\/h3>\n\n\n\n<p>The number of atoms in 1.4 millimoles of PF\u2083 is approximately <strong>3.37 \u00d7 10\u00b2\u00b9 atoms<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>This calculation uses basic principles of mole concept and Avogadro\u2019s number to convert between moles, molecules, and atoms. By understanding the molecular composition of PF\u2083 and recognizing the relationship between moles and particles, we can determine the total number of atoms in a given amount of substance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How many atoms are one 1.4 mil of phosphorus trifluoride (PF3) The correct answer and explanation is: To determine the number of atoms in 1.4 millimoles (mil) of phosphorus trifluoride (PF\u2083), follow these steps: Step 1: Understand the Molecular Composition of PF\u2083 Phosphorus trifluoride (PF\u2083) is a molecular compound made up of one phosphorus (P) [&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-44787","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/44787","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=44787"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/44787\/revisions"}],"predecessor-version":[{"id":44788,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/44787\/revisions\/44788"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=44787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=44787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=44787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
