Answer: The concentartion of solution will be 0.224 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute =
= volume of solution in ml = 275 ml
Now put all the given values in the formula of molarity, we get
Therefore, the concentration of solution will be 0.224 M
Object one will float because the mass and volume are lighter than object two. Object one also has a smaller surface area.
The correct answer would be C. a precipitate
Hope this helped!
Answer: The final pressure is 0.81 kPa
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 0.58 kPa
= final pressure of gas = ?
= initial volume of gas = v
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 0.81 kPa
Answer:
i think it's C or D.
Explanation:
but if I had to choose i would pick D. sorry if it's wrong. but i hope it's right.
