Explanation:
what game is this i have never saw this game
Answer:- 0.0634 M
Explanation:
molarity is defined as the number of moles of solute in 1 L of solution
molar mass of Ni(NO₃)₂ - 182.7 g/mol
number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol
number of moles in 500 mL - 0.0317 mol
therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L
molarity of the solution is - 0.0634 M
The correct answer to what additional measurement the student requires is; D. The student has enough information to make the determination
<h3>Understanding Change in Momentum</h3>
Formula for change in momentum is;
ΔP = m(v - u)
Now, this change in momentum is also equal to impulse which has the formula; Impulse = Force(F) × Time(t)
I = F × t
Thus;
m(v - u) = F × t
Now, we are given;
Force exerted on the object and the time interval. Thus;
ΔP = F × t
Thus, the student has enough information to find the change in momentum
The missing options are;
a. The mass of the object.
b. The final speed of the object MOH 5000
c. The distance fallen by the object
d. The student has enough information to make the determination
