Answer:
<h2>6426000 mg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
63 mL = 63 cm³
We have
mass = 102 × 63 = 6426
But 1 g = 1000 mg
6426 g = 6426000 mg
We have the final answer as
<h3>6,426,000 mg</h3>
Hope this helps you
B seems like the correct answer stay safe!
Answer: Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Answer:
1.7927 mL
Explanation:
The mass of solid taken = 4.75 g
This solid contains 21.6 wt%
, thus,
Mass of
=
= 1.026 g
Molar mass of
= 261.337 g/mol
The formula for the calculation of moles is shown below:
Thus,

Considering the reaction as:

1 moles of
react with 1 mole of 
Thus,
0.003926 mole of
react with 0.003926 mole of 
Moles of
= 0.003926 mole
Also, considering:

Molarity = 2.19 M
So,

Volume = 0.0017927 L
Also, 1 L = 1000 mL
<u>So, volume = 1.7927 mL</u>
