A sample compound contains 9.11 g Ni and 5.89g F. What is the empirical formula of this compound?
Alexxx [7]

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

A piece of PVC plumbing pipe displaces 60 mL when placed into a container of water. If the pipe has a mass of 78g, what is the d
babymother [125]
Use the equation d=m/v

your mass or "m" is 78 g

your volume or "v" is 60mL

if you plug those values into the equation it will look like this:

d=78/60
d=1.3g/mL should be what you come up with
