Question

14. How many moles of Cu(NO3)2 are contained in 400.0 mL of 0.90 M Cu(NO3)2.

Answer 1

`0.36\text{ mole}`

Step-by-step explanation:

Here, we want to get the number of moles contained

To get this, we have to multiply the volume in L by the molarity

Mathematically, we have that as:

`moles\text{ = volume * molarity}`

We have this as:

`moles\text{ = }(400)/(1000)\text{ }*\text{ 0.90 = 0.36 mole}`
