''The belt also needed an immovable anchorage point for the buckle as far down beside the occupant's hip, so it could hold the body properly during a collision.
Answer: 0.125moles
Explanation:
From the question above, we are only given the values of the volume and molar concentration of CuSO4 solution.
Volume of CuSO4 solution = 250mL= 250/1000L = 0.25L
Molar concentration of CuSO4 solution= 0.50M
Number of moles of CuSO4= Molar concentration of CuSO4 × volume of CuSO4
Number of moles of CuSO4= 0.50mol/dm^3 × 0.25L
Number of moles of CuSO4= 0.125moles
Therefore 0.125moles of CuSO4 are used to make 250 mL of a 0.50M CuSO4 solution.
Answer: A
Explanation: A switch is in an improper position when the switch pole screw lies against the switch box and the runner is shorted, which causes the fuse to blow when you turn the lights off.
Density = Mass/Volume
d = .254/129.4
