Answer:
Precipitate
Explanation:
A precipitate is a solid formed from a chemical solution
Answer:
20.3 % NaCl
Explanation:
Given data:
Mass of solute = 45.09 g
Mass of solvent = 174.9 g
Mass percent of solution = ?
Solution:
Mass of solution = 45.09 g + 174.9 g
Mass of solution = 220 g
The solute in 220 g is 45.09 g
220 g = 2.22 × 45.09
In 100 g solution amount of solute:
45.09 g/2.22 = 20.3 g
Thus m/m% = 20.3 % NaCl
Answer:
flocculation is the operation in which the coagulated water must be gently mixed at a propeller speed of 15 to 20 rpm to promote the growth of the floc. ... The flocculation basin often has a number of compartments with decreasing mixing speeds as the water advances through the basin.
Explanation:
<u>Answer:</u> The given mass in kilograms is 0.00399 kg
<u>Explanation:</u>
Gram and Kilograms are the units which are used to express the mass of a substance. These units are inter changeable.
We are given:
Mass of a substance = 3.99 g
To convert the given mass into kilograms, we use the conversion factor:
1 kg = 1000 g
Converting the given value, we get:
Hence, the given mass in kilograms is 0.00399 kg
