Can you give me the anwsers
The question here is solved using basic chemistry. CaCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of CaCl2 that dissolves.
CaCl2(s) --> Ca+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.65 mol CaCl2/1L × 2 mol Cl⁻ / 1 mol CaCl2 = 1.3 M
The answer to this question is [Cl⁻] = 1.3 M
What subject is this again ? If I know now then I would have a better understanding of what I’m gonna answer so you don’t get it wrong !
Answer:
0.016 m³
Explanation:
Step 1: Given data
Width of the tank (w): 18 in
Height of the tank (h): 11 in
Depth of the tank (d): 5 in
Step 2: Calculate the volume of the tank in in³
The fuel tank is a cuboid. We can calculate its volume using the following expression.
V = w × h × d
V = 18 in × 11 in × 5 in
V = 990 in³
Step 3: Convert 990 in³ to m³
We will use the relationship 1 m³ = 61023.7 in³.
990 in³ × (1 m³ / 61023.7 in³) = 0.016 m³
