Answer:
The answer to your question is 71.22 g
Explanation:
Data
Density = 19.3 g/cm³
Volume = 0.00369
mass = ?
Formula
Density =
Solve for mass
mass = density x volume
Process
1.- Convert volume from liters to cubic centimeters
1 l ---------------- 1000 cm³
0.00369l --------- x
x = (0.00369 x 1000 ) / 1
x = 3.69 cm³
2.- Substitution
mass = 19.3 x 3.69
3.- Simplification and result
mass = 71.22 g
<h2>0.72 mol/L</h2>
Explanation:
We are given a solution which contains
of
.
To calculate number of moles of present, we need to find it's molar mass from charts. Molar Mass of
is known to be
.
Number of moles of present =
Molarity =
∴ Molarity of given solution =
