Answer:

M(AgNO3) = 169,8731 g mol

Explanation:

M(Ag) = 107,8682 g mol

M(N) = 14.0067 g mol

M(O) = 15.9994 g mol

M(AgNO3) = M(Ag) + M(N) + 3 x M(O) = 107.8682 + 14.0067 + 3 x 15.9994 =

= 169,8731 g mol

Just sum up all the respective elements' molar mass.

For scientific notation, when i move the decimal to the left the the exponent get bigger or smaller?
xeze [42]
I'm not sure what you mean. Besides, I feel like you're talking math.
But anyways, if you have 120 let's say
The scientific notation is 1.20 × 10^2
if you have 125000
the scientific notation is 1.25 × 10^ 5
The number of times you go left the decimal, I guess exponent increases
So yea

. If 12 oranges cost $36.00, what is the cost for 20 oranges?
Olegator [25]

Answer:

60 dollars!

Explanation:

So, 12 oranges cost $36 dollars.

Now, we can solve this by finding the value for only <u>one</u> orange, then multiplying that by 20 to get our answer!

So, the value of one orange is $36 / 12 = $3. One orange is worth $3 dollars.

So, 20 oranges will be worth 20 * 3 = $60 dollars!

Determine the energy in joules or a photon with frequency of 5.78 x 10^17 Hz​
xenn [34]

Answer:

E= 3.829 x 10-16 J

Explanation:

Data Given

Frequency= 5.78 x 10^17 Hz

Energy in joules = ?

Solution:

Formula used to calculate Energy

E= hv…………….. (1)

Where E is Energy

h is Planks Constant = 6.626 x 10–34 J s

v is frequency

The given frequency is in Hz (Hertz)

Hz is equal to s-1 (per second)

1 hertz = 1 /second

Putting the values in Equation 1

E= (6.626 x 10–34 J s) (5.78 x 1017 s-1)

E= 3.829 x 10-16 J
