Answer:
B and C
Step-by-step explanation:
138 dolllars multiply 115 and .20 and add your answer with the original amount
1 litre = 1000 ml
4.6 litre = 4600 ml
4600 / people = how much she should pour into each glass
Decay expression is stated as follows:
N(t) = N(o)e^(-0.693t/t1/2)
N(t) = Quantity remaining after time, t; N(o) = Initial quantity, t = time, t1/2 = Half life
Therefore,
N(6.55) = 2*e^(-0.693*6.55/5.2) = 0.835 g
