prettty sure this is wrong but eh :/ probably correct
pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.
<h3>What is pH?</h3>
pH is helps to determine if a solution is acidic or basic in nature.
A pH meter is the instrument that can be used for the measurements.
Methyl orange is used when titrating a strong acid against a weak base.
Therefore, the pH of the solution which is a weak acid will be between 4.0-7.0.

Answer:
15.14×10⁷ g
Explanation:
Given data:
Number of particles of NaCl = 1.56×10³⁰ particles
Mass of sodium chloride = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ particles
1.56×10³⁰ particles × 1 mol / 6.022 × 10²³ particles
0.259 ×10⁷ mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.259 ×10⁷ mol × 58.44 g/mol
Mass = 15.14×10⁷ g
this is what i foudn-By its definition as a homogeneous solid, a mineral is composed of a single solid substance of uniform composition that cannot be physically separated into simpler chemical compounds. ... Most rocks are composed of several different minerals; e.g., granite consists of feldspar, quartz, mica, and amphibole.
hope this is helpful.
