The grams of 22.9 % sugar solution that contain 68.5 g of sugar is 299.13 g of solution
<u><em>calculation</em></u>
22.9% means that there are 22.9 g of sugar in 100 g of solution.
what about 68.5 g of sugar
- <em>by cross multiplication</em>
=[(68.5 g sugar x 100 g solution) /22.9 g sugar] =299.13 g of solution
Nb; <em>g sugar cancel each other</em>
Answer:
The answer is C. An electrochemical cell.
Explanation:
The aluminum ion react with the sulfide to form aluminum sulfide.
What is the element with 7 protons? They probably also have 7 neutrons. Just a ball park figure guess.
An Organic Compound is when Hydrogen and Nitrogen are bonded.
Therefore A is the answer
Solution: (a) The net force is zero because car is travelling with same speed that is 60 miles per hour or there is no acceleration.
(b) Mass of object is 10 kg
Acceleration is 2 m/s², thus force can be calculated as follows:
F=m×a
Here, m is mass of object and a is its acceleration thus,
F=10 kg×2 m/s²
=20 kg m/s²
Here, 1 N=1 kg m/s²
Thus, F=20 N
(c) Force on object is 17 N and its acceleration is 1.5 m/s².
Mass of the object can be calculated as follows:
m=\frac{F}{a}
thus,
m=\frac{17 N}{1.5 m/s^{2}}=11.33 (\frac{N}{m/s^{2}})
Here, 1 N=1 kg m/s²
Thus,
m=11.33 kg
