The mass percentage of water (H₂O) in cadmium chloride tetra hydratesolution is equal to the 28.2%.
<h3>How do we calculate mass percentage?</h3>
Mass percentage of any substabce present in any solution will be calculated as:
Mass percent = (Mass of substance/Total mass of solution)×100%
According to the question,
Mass of water (H₂O) = 18.02 g/mol
Mass of solvent (CdCl₂.4H₂O) = 183.32 + 4(18.02) = 255.4 g/mol
On putting values, we get
Mass percent = (18.02 / 255.4) × 100% = 28.2%
Hence mass percent of water is 28.2%.

Do according to bodmas rule
Answer:
Aside from the sun, the water cycle is driven by the transpiration in plants and respiration in humans. Humans and animals both release water vapor in the atmosphere.

Given parameters:
Density = 2.7g/cm³
Length of the cube = 10cm
Unknown:
Mass of the cube = ?
Solution:
Density is the mass per unit volume of a substance.
Density = 
Mass = density x volume
We need to find the volume of the cube;
Volume of the cube = L³
where L is the length of the cube;
Volume of the cube = 3³ = 27cm³
So, the mass of the granite = 2.7 x 27 = 72.9g
The granite has a mass of 72.9g
