Answer:
648.5 mL
Explanation:
Here we will assume that the pressure of the gas is constant, since it is not given or specified.
Therefore, we can use Charle's law, which states that:
"For an ideal gas kept at constant pressure, the volume of the gas is proportional to its absolute temperature"
Mathematically:
![\frac{V}{T}=const.](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BT%7D%3Dconst.)
where
V is the volume of the gas
T is its absolute temperature
The equation can be rewritten as
![\frac{V_1}{T_1}=\frac{V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D)
where in this problem we have:
is the initial volume of the gas
is the initial temperature
is the final temperature
Solving for V2, we find the final volume of the gas:
![V_2=\frac{V_1 T_2}{T_1}=\frac{(490)(315)}{238}=648.5 mL](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7BV_1%20T_2%7D%7BT_1%7D%3D%5Cfrac%7B%28490%29%28315%29%7D%7B238%7D%3D648.5%20mL)
Uranium, most uranium does derive from a star. However, not from our sun.
Answer:
The answer is 2.660 mol/l
Explanation:
Given: n= 0.0665, v= 25.00ml
Required: C
C (molarity)= n (of solute)/ v (of solvent) [ standard unit: mol/l]
First convert volume of solvent in its standard unit, i.e. litres(L)
v= 25.00ml/1000= 0.02500L
C = 0.0665 mol / 0.02500 L= 2.660 mL (In proper significant digits i.e. 4 sigdigs)
Therefore, The molarity of the sulfuric acid is 2.660 mol/L :)
