What is the weight in grams of 3.36*10^23 molecules of copper sulfate

The weight in grams of molecules of copper sulfate is 89.023 g.

Step-by-step explanation:

Given :  Molecules of copper sulfate

To find : What is the weight in grams of molecules of copper sulfate?

Solution :

Molar mass of copper sulfate ()

Cu=63.5

S=32

O=16

We know, that 1 mole = Avogadro number

1 mole = molecules

 molecule weigh = 159.5 g

1 molecule weigh = g

So, molecule weigh = g

g

g

g

Therefore, The weight in grams of molecules of copper sulfate is 89.023 g.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
