Sedimentary rocks are the only rocks that can hold fossils.
500 mg in g :
1 g ----------- 1000 mg
? -------------- 500 mg
500 x 1 / 1000 => 0.5 g
total mass:
50 g + 0.5 g + 0.1 g => 50.6 g
hope this helps!
You didn’t put a diagram up
Answer:
<h3>The answer is 1.63 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual mass = 9.80 g
error = 9.80 - 9.64 = 0.16
We have
We have the final answer as
<h3>1.63 %</h3>
Hope this helps you
one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol. This means that every mole of sulfuric acid has a mass of 98.0795 g. Since you're dealing with one mole of sulfuric acid, it follows that you will also be dealing with two moles of hydrogen.
