Answer: 1.38 moles

Explanation: According to Avogadro's law, 1 mole of every substance contains Avogadro number of particles (atoms, molecules or ions) i.e. 6.023\times 10^{23} particles.

Given : 1 mole molecule of water contains 6.023\times 10^{23} molecules of water.

6.023\times 10^{23} molecules are present in = 1 mole

8.30\times 10^{23}  molecules will be present in =\frac{1}{6.023\times 10^{23}}\times 8.30\times 10^{23}=1.38 moles

Thus 8.30\times 10^{23} molecules is equal to 1.38 moles.

You multiply avogadro's number to what you were given.
8.30x10^23 * 6. 0221409x10^23
=1.357*10^25

That should be the right answer but I'm not sure. It has been awhile since I have done this.

HELP Consider this equation...
Mashcka [7]

Answer:

it is not correct I have an answer for ''why''

Explanation:

You need to balance it

s= 2

0=2

S+30•2 --------> SO•3

2 2 2 2

S +3O•2-------->SO•2......MULTIPLY

2 4 2 4......LCM IS 4

2 1 2 1....DIVIDE BY 4

SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.

2S+3O•2 -----> 2SO•3

now you can check the both sides its balances the correct answer is this
