The empirical formula of the compound is C. NiF₂.
<em>Step 1</em>. Calculate the <em>moles of each element</em>
The empirical formula is the simplest whole-number ratio of atoms in a compound.
The ratio of atoms is the same as the ratio of moles.
So, our job is to calculate the molar ratio of Ni to F.
Moles of Ni = 9.11 g Ni × (1 mol Ni /(58.69 g Ni) = 0.1552 mol Ni
Moles of F = 5.89 g F × (1 mol F/19.00 g F) = 0.3100 mol F
<em>Step 2</em>. Calculate the <em>molar ratio</em> of the elements
Divide each number by the smallest number of moles
Ni:F = 0.1552:0.3100 = 1:1.997 ≈ 1:2
<em>Step 3</em>: Write the <em>empirical formula</em>
EF = NiF₂
Answer:
34.9103 or 34.9 g
Explanation:
Remember Density is a broken heart: m/v.
In this scenario (Let x = # of grams in the sample of gasoline),
D = 0.7198 g/mL = x g / 48.5 mL
So,
(0.7198 g/mL) * (48.5 mL) = x g
x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
The answer for the equation given is 1.743488.
<h3>Equation :</h3>
10,000/ 5,735.63 = 1.743488.
<h3>How are units labeled?</h3>
Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.
<h3>What is label in math means?</h3>
A graph labelling is the process of assigning labels, which are typically represented by integers, to the edges and/or vertices of a graph in the field of mathematics known as graph theory.
