D= M/V so, D=300/40 wich is 7.5 so D= 7.5g/m3
Answer:
The answer is
<h2>53.56 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of rock = 316 g
density = 5.9 g/mL
The volume of the rock is
We have the final answer as
<h3>53.56 mL</h3>
Hope this helps you
In one meter, there is 10000 milimeters. Just multiply however many meters you have by 10000, and youll have your answer.

<h3>What is a neutralization reaction?</h3>
A neutralization reaction is a reaction between an acid and a base to form salt and water only.
The reaction between vinegar and NaOH is a neutralization reaction which produces a salt and water only.
NaOH is composed of a positive sodium ion, Na+ and a negative hydroxide ion, OH-
Therefore, the negative ion in the NaOH(aq) used in this titration is hydroxide ion, OH-.
