Answer:
Approximately .
Explanation:
This question can be solved using Hess's Law.
Start by considering: how can the first three reactions (with known values) be combined to produce the reaction
?
Here's one possible combination:
- Include the first reaction once, without inverting.
- Invert the second reaction and include it once.
- Include the third reaction after multiplying all its coefficients by two.
In other words, if ,
, and
denote the three reactions with know
values, respectively, then
will give the required reaction
.
By Hess's Law, the value of the reaction
will thus be:
.
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
