Density is defined as mass per unit volume.
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
Answer:
CaCl2 + 2AgNO3 = Ca(NO3)2 + 2AgCl
Explanation:
Calcium chloride react with silver nitrate to produce calcium nitrate and silver(1) chloride
The average atomic mass of chromium to 3 decimal points is 52. 055 g. mol.
<h3>What is the average atomic mass?</h3>
"The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight."
Given the different isotopes of chromium.
The four isotopes of chromium are cr-50, cr-52, cr-53 cr-54.
The average atomic mass will be
Let us take the weighted average of your isotopes:
50 × 0.0434 + 52 × 0.8379 + 53 × 0.095 + 54 × 0.0237 = 52. 055 g.
Thus, the average atomic mass of chromium is 52. 055 g.
