whole-number ratio of elements in a compound. formula. For example, a compound that has an empirical formula of CH2O may have a molecular formula of C2H4O2, C3H6O3, C4H8O4
Answer:
[HClO₄] = 11.7M
Explanation:
First of all we need to know, that a weight percent represents, the mass of solute in 100 g of solution.
Let's convert the mass to moles → 70.5 g . 1mol/100.45 g = 0.702 moles
Now we can apply the density to calculate the volume.
Density always refers to solution → Solution density = Solution mass / Solution volume
1.67 g/mL = 100 g / Solution volume
Solution volume = 100 g / 1.67 g/mL → 59.8 mL
To determine molarity (mol/L) we must convert the mL to L
59.8 mL . 1L/1000mL = 0.0598 L
Molarity → Moles of solute in 1L of solution → 0.702 mol / 0.0598 L = 11.7M

A sedentary lifestyle is a lifestyle type characterized by abundant sedentary behaviors. People who live a sedentary life often sit or lie down for most of the day in activities such as socializing, watching TV, playing video games, reading books, and using mobile phones and computers.
A sedentary lifestyle can lead to high blood pressure, low cholesterol, and elevated blood sugar levels, which damage the walls of blood vessels and increase the risk of a heart attack.

Density = Mass / Volume
Density = 2.74g / 3.10cm³
Density = 0.88 g/cm³
Answer:
The forward reaction will be favored.
Explanation:
The reaction is:
As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.
a) If we increase pressure, the volume will decrease.
b) Due to decrease in volume, the moles per unit volume will increase.
c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]
d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.
e) Thus forward reaction will be favored.
