Answer:
Explanation:
Initial burette reading = 1.81 mL
final burette reading = 39.7 mL
volume of NaOH used = 39.7 - 1.81 = 37.89 mL .
37.89 mL of .1029 M NaOH is used to neutralise triprotic acid
No of moles contained by 37.89 mL of .1029 M NaOH
= .03789 x .1029 moles
= 3.89 x 10⁻³ moles
Since acid is triprotic , its equivalent weight = molecular weight / 3
No of moles of triprotic acid = 3.89 x 10⁻³ / 3
= 1.30 x 10⁻³ moles .

To calculate the average mass of the element, we take the summation of the product of the isotope and the percent abundance. In this case, the equation becomes 186.207=187*0.626+185*x where x is the percent abundance of 185. The answer is 0.374 or 37.4%. This can also be obtained by 100%-62.6%= 37.4%.
Answer:
1.0975 atm.
Explanation:
<em>According to Boyle’s Law:</em> "
At constant temperature , the volume of a given quantity of a gas varies inversely with its pressure".
P α 1/V.
<em>∴ P₁V₁ = P₂V₂.</em>
P₁ = 4.39 atm, V₁ = 0.5 L.
P₂ = ??? atm, V₂ = 2.0 L.
<em>∴ P₂ = P₁V₁/V₂</em> = (4.39 atm)(0.5 L) / (2.0 L) = <em>1.0975 atm.</em>
