So let's use some equations to represent the data [let R= cost of ring & B= cost of bracelet]
R= B + $ 36 .... (1)
B=
× R ... (2)
By using simultaneous equations to solve for B and R.
Substitute eq. (1) into eq. (2)
B = × (B + $36)
B =B + 
⇒ B = $48
By substituting value of B into ea (1)
If R = B + $36
R = ($48) + $36
= $84
∴ <span> the total of the two items = R + B
= $84 + $48
</span> = $132
R= B + $ 36 .... (1)
B=

Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of
The given chemical equation is -
--------- 2
Now , calculation -
Mass of formed = 118g
Molar mass of =
Mole =
Therefore , moles of formed =
From equation 2 , we get to know that ,
2mole formed from 5 mole
Therefore , mole
formed from
mole
Moles of used =
R=
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of (n)=
moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -
V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
