Answer:
The volume will be 89.6875 ml
Explanation:
So to count this we will use a single proportion.
0.0640 mol - 1000 ml
5.74×10−3 mol - x ml
x ml=5.74×10−3 mol*1000 ml/0.0640 mol=89.6875 ml
Answer:
Yes
Explanation:
They continue to split and grow and split again until the organism that is carrying them dies.
Sorry I don't really know how to explain:(
A, B, and C are insoluble in water
