<span> by putting values from periodic tabl H2(2 x 1.007947 g H/mol ) + S(32.0655 g S/mol) + 04(4 x 15.99943 g O/mol) =
98.0791 g H2SO4/mol is the answer hope it helps</span>
Here are some simple equations that can be a life saver with this stuff :
vol of a sphere =
![v = \frac{3}{4} \pi \: {r}^{3}](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cpi%20%5C%3A%20%7Br%7D%5E%7B3%7D%20)
Circumference =
![2 \times \pi \times r](https://tex.z-dn.net/?f=2%20%5Ctimes%20%5Cpi%20%5Ctimes%20r)
sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
Answer:
Your answer is: (-1/2, 3/2)
Step-by-step explanation:
y = x + 2
y = -3x
Use substitution by plugging the second equation into the first.
-3x = x +2
Subtract x from both sides to combine the variables.
-4x = 2
Divide both sides by -4 to isolate the variable x.
x = 2/-4
Simplify.
x = -1/2
Plug x into one of the equations to find y.
y = (-1/2) + 2
y = 3/2
Plug x into the other equation to confirm your answer.
y = -3(-1/2)
y = 3/2
Your answer is: (-1/2, 3/2)
Answer:
c
