<h3>
Answer:</h3>
61.3 mL
<h3>
Explanation:</h3>
From the data given;
- Mass of volumetric flask is 109.1 g
- Mass of salt is 5.01 g
- Mass of Volumetric flask and salt is 113.5 g
- Mass of volumetric flask and salt solution is 170.4 g
- Mass of salt solution is 61.3 g
We are required to calculate the volume of salt solution;
We need to know the relationship between density, mass and volume of a solution.
Density = Mass ÷ Volume
Therefore, given mass and density we can find the volume.
Rearranging the formula;
Volume = Mass ÷ density
Assuming the density of salt solution is 1 g/mL
Then;
Volume = Mass of the salt solution ÷ density of the salt solution
= 61.3 g ÷ 1 g/mL
= 61.3 mL
Therefore, the volume of the salt solution is 61.3 mL
Answer:
The density increases.
Explanation:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
The reaction mixture of problem 1 includes <span>10mL of 4.0 M acetone = 10 mL 1.0 M HCl = 10 mL 0.0050 M I2 = 20 mL H2O. if this is true then the procedure is the following:
In order to find the total volume of reaction then you need to do like this:
</span><span>V = 10 mL + 10 mL + 10 mL + 20 mL = 50 mL </span>
<span>[I2]o = (0.005 mol I2 / 1 L I2 solution) (10 mL I2 solution) / 50 mL = 0.001 M </span>
<span>To first order, the reaction rate is 0.001 M / 230 s = 4,3 e-6 M/s
Then if you want to find the rate yoe need to use the following formula:
</span><span> k [CO(CH3)2]^a [I2]^b [HCl]^c
</span>So: <span>4,3 e-6 = k (4 M * 10 mL / 50 mL)^a (1e-3 M)^b (1 M * 10 mL / 50 mL)^c
</span>

Answer:
1.33 × 10⁻³ m³
Explanation:
Step 1: Given data
Side of the cube (d): 11.0 cm
Step 2: Calculate the volume of the cube (V)
We will use the following expression.
V = d³
V = (11.0 cm)³
V = 1.33 × 10³ cm³
Step 3: Convert "V" to m³
We will use the conversion factor 1 m³ = 10⁶ cm³.
1.33 × 10³ cm³ × (1 m³ / 10⁶ cm³) = 1.33 × 10⁻³ m³
