The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To determine how many Te atoms are in 3.03 g of TeO2, follow these steps:<\/p>\n\n\n\n

    \n
  1. Calculate the molar mass of TeO2:<\/strong>
    • Molar mass of Te = 127.6 g\/mol<\/li>
    • Molar mass of O = 16.00 g\/mol<\/li>
    • TeO2 has one Te atom and two O atoms. So, the molar mass of TeO2 is:<\/li><\/ul>Molar\u00a0mass\u00a0of\u00a0TeO2=127.6+(2\u00d716.00)=127.6+32.00=159.6\u2009g\/mol\\text{Molar mass of TeO2} = 127.6 + (2 \\times 16.00) = 127.6 + 32.00 = 159.6 \\, \\text{g\/mol}Molar\u00a0mass\u00a0of\u00a0TeO2=127.6+(2\u00d716.00)=127.6+32.00=159.6g\/mol<\/li>\n\n\n\n
    • Calculate the number of moles of TeO2 in 3.03 g:<\/strong>
      • Moles of TeO2 = Mass\u00a0of\u00a0TeO2Molar\u00a0mass\u00a0of\u00a0TeO2\\frac{\\text{Mass of TeO2}}{\\text{Molar mass of TeO2}}Molar\u00a0mass\u00a0of\u00a0TeO2Mass\u00a0of\u00a0TeO2\u200b<\/li><\/ul>Moles\u00a0of\u00a0TeO2=3.03159.6=0.01898\u2009mol\\text{Moles of TeO2} = \\frac{3.03}{159.6} = 0.01898 \\, \\text{mol}Moles\u00a0of\u00a0TeO2=159.63.03\u200b=0.01898mol<\/li>\n\n\n\n
      • Calculate the number of moles of Te atoms:<\/strong>
        • Each mole of TeO2 contains 1 mole of Te atoms (because there is 1 Te atom per TeO2 molecule).<\/li><\/ul>Moles\u00a0of\u00a0Te=0.01898\u2009mol\\text{Moles of Te} = 0.01898 \\, \\text{mol}Moles\u00a0of\u00a0Te=0.01898mol<\/li>\n\n\n\n
        • Calculate the number of Te atoms:<\/strong>
          • Avogadro\u2019s number = 6.022\u00d71023\u2009atoms\/mol6.022 \\times 10^{23} \\, \\text{atoms\/mol}6.022\u00d71023atoms\/mol<\/li><\/ul>Number\u00a0of\u00a0Te\u00a0atoms=Moles\u00a0of\u00a0Te\u00d76.022\u00d71023\\text{Number of Te atoms} = \\text{Moles of Te} \\times 6.022 \\times 10^{23}Number\u00a0of\u00a0Te\u00a0atoms=Moles\u00a0of\u00a0Te\u00d76.022\u00d71023 Number\u00a0of\u00a0Te\u00a0atoms=0.01898\u00d76.022\u00d71023=1.14\u00d71022\\text{Number of Te atoms} = 0.01898 \\times 6.022 \\times 10^{23} = 1.14 \\times 10^{22}Number\u00a0of\u00a0Te\u00a0atoms=0.01898\u00d76.022\u00d71023=1.14\u00d71022<\/li>\n<\/ol>\n\n\n\n

            Thus, the number of Te atoms in 3.03 g of TeO2 is 1.14E22<\/strong>.<\/p>\n\n\n\n
