Answer:
The answer is
<h2>111.52 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of mercury = 13.6 g/cm³
First we must convert the volume from mL to cm³
if 1 mL = 1 cm³
Then 8.20 mL = 8.20 cm³
volume = 8.20 cm³
The mass of mercury is
mass = 13.6 × 8.2
We have the final answer as
<h3>111.52 g</h3>
Hope this helps you
Answer:
C₆H₁₈
Explanation:
Let's say x is the subscript of carbon and y is the subscript of hydrogen. We know from the empirical formula that the ratio of x to y is 2 to 6.
x / y = 2 / 6
We also know from the molar mass that:
12.01x + 1.01y = 90.21
Solving the system of equations:
2y = 6x
y = 3x
12.01x + 1.01(3x) = 90.21
12.01x + 3.03x = 90.21
15.04x = 90.21
x = 6
y = 3x
y = 18
The molecular formula is therefore C₆H₁₈.
