Answer:
<h2>106.62 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 = 83.7 g
density = 0.785 g/mL
We have

We have the final answer as
<h3>106.62 mL</h3>
Hope this helps you
Answer:
E - Atomic mass is calculated by weighted atomic average using all the isotope data available.
G - Mass number is equal to the sum of protons and electrons in an atom.
Explanation:
Take an element

- Mass no is 25 and atomic no is 12.
The substance that contains hydrogen that may be replaced by a metal is an acid~
The mass percent of sulfurous acid in the new solution : 38.9%
<h3>Further explanation</h3>
<em>In a container you have 800 g of a 35% by mass solution of sulfurous acid, from which 80 ml of water evaporates. What is the mass percent of sulfurous acid in the new solution? data: density of water is 1g / ml.</em>
