Answer:
what would the question be?
Answer:
D
Explanation:
The electrons revolve around the nucleus and they contain negative charge
0.115 M means that 0.115 moles of KBr are contained in a volume of 1000 ml, therefore a volume of 350 ml will have (0.115 × 0.35) = 04025 moles
From the formula of molarity moles = molarity × volume in liters
1 mole of KBr is equivalent to 119 g
Therefore, the mass = 0.04025 × 119 g = 4.79 g
Answer:
B
Explanation:
the gravitational force is a big play.
