2 answers:
<h2>Answer:</h2>
The mass in grams of C8H18 is 672.6g.
<h3>Explanation:</h3>
Given data:
Number of moles = 5.90
Molecular mass = 114 grams in one mole.
Mass in grams= ?
Solution:
Molecular mass of an element is the mas in grams of element in one mole. Hence the mass in grams in 5.9 mole will be equal to the number of moles multiplied by molecular mass.
Hence in the numerical for:
Mass in grams= Molecular mass × Number of moles.
Mass in grams= 114× 5.90 = 672.6 g
Hence the mass in grams is 673 g.
Mass = 5.90 x 114 = 672.6g .
This can be rounded to <em>673g</em>
<em>C = 12 grams x 8 = 96 grams </em>
<em>H = 1 gram x 18 = 18 grams </em>
<em>Total = 96 + 18 = 114 grams in one mole. </em>
<u>If you have 5.9 moles, multiply this by the weight of one mole (114 grams) = 672.6 rounded to 673 grams in 5.9 moles. </u>

Answer:
<h2>0.06 % </h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
error = 500 - 499.7 = 0.3
actual volume = 500 mL
We have
We have the final answer as
