Answer:
The answer is
<h2>0.63 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 47 g
volume = 75 mL
The density is
We have the final answer as
<h3>0.63 g/mL</h3>

0.3 L is the final volume when M₁ = 3 M, V₁ = 0.125L, M₂ = 1.25M.
<h3>What is volume?</h3>
The amount of space occupied by a three-dimensional figure as measured in cubic units.
Given data:
M₁ = 3 M
V₁ = 0.125L
M₂ = 1.25M
V₂ = ?
Solution:
M₁V₁ = M₂V₂
3 M × 0.125L = 1.25M × V₂
V₂ = 0.3 L
Hence, 0.3 L is the final volume.

Answer:
A small amount of solute dissolved in a larger amount of solvent.
Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.
POH will be -log[conc of OH]
-log (3.9E-08) = 7.409
pH = 14- pOH
pH = 14 - 7.409
pH = 6.59
