Answer:

Mass = 159.8 g

Explanation:

Given data:

Mass of HNO₂ = ?

Moles of nitrous acid = 3.4 mol

Solution:

Formula:

Number of moles = mass / molar mass

We will rearrange this formula.

Mass = number of moles × molar mass

Molar mass of nitrous acid =  47 g/ mol

Mass = 3.4 mol × 47 g/ mol

Mass = 159.8 g

Determine the [OH−] , Ph, and POH of a solution with a [H+] of 0. 00017 m at 25 °C.
tino4ka555 [31]

Main Answer:

Given

pH = -log[H+]

= -log[0.00017]

= 3.769

We know that

pW = pH + pOH

and pW =14

pOH = 14-pH

=14-3.769

=10.231

According to the definition

pOH = -log[OH-]

10.231 = log[OH-]-1

[OH-]= 5.87 x 10-11

Explanation:

What is pH?

pH is defined as the concentration of H+ ion in the solution. If the pH value is less than 7, then the solution will be acidic. If the pH value is greater than 7, then the solution will be basic.

Why is water called "the universal solvent" and why is this important for living things?
Aleks [24]
As it dissolves a large number of solid, liquid and gaseous substances it's called a universal solvent. It's important for living thing because all of them depend on water to survive. For example, many organisms live in the water and they find some of the nutrients that are necessary for live dissolved in water - gases included.
