1) 0.89% m/v = 0.89 grams of NaCl / 100 ml of solution
=> 8.9 grams of NaCl in 1000 ml of solution = 8.9 grams of NaCl in 1 liter of solution
2) Molarity = M = number of moles of solute / liters of solution
=> calculate the number of moles of 8.9 grams of NaCl
3) molar mass of NaCl = 23.0 g /mol + 35.5 g/mol = 58.5 g / mol
4) number of moles of NaCl = mass / molar mass = 8.9 g / 58.5 g / mol = 0.152 mol
5) M = 0.152 mol NaCl / 1 liter solution = 0.152 M
Answer: 0.152 M
Answer:
The negative from object A must transfer to object B
Explanation:
Voltage difference is the push that causes charges to flow from high to low areas.
This are letters of the alphabet some are periods and some are commas also they do not form any words or meaning
hope this helped ;)
Answer:
The answer is "power dispatcher."
Explanation:
"Power dispatchers" are also known as <em>"power distributors</em>." Their field of work is related to controlling the distribution of electricity to the <em>"electrical substations." </em>These substations allow the transmission of electricity to step down from a higher voltage to a lower voltage.
Whenever there is an electrical problem, the power dispatcher also comes into play. They make sure that the power lines are intact and checks for possible damages when typhoons or earthquakes occur.
Thus, this explains the answer.
