The answer is “decreasing mass by one unit”
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms</span>
Density as you should know is equal to mass/volume. Solve for the volume.
Now, you know that you are dealing with a sphere. You know the volume of a sphere is V= 4/3pi r ^3.
You know the volume so just solve for r
Answer:
<h2>Sodium Chloride (NaCl)</h2>
Explanation:
Using the standard solubility table , the solubility of sodium chloride is 36 g/100 mL water at 25°C.
Which means that 1 g of solid(that is in crystal form) sodium chloride will dissolve in 100 mL of water at 25°C.
