Step 2: Use Dimensional Analysis
= 500 mL
Answer:
5)0.53liters
6)1.634.6°c
Explanation:
5) v1=25liters, t1=12000°c. v2=?, t2=250°c
v2=(250×25)/12000
v2=6250/12000
v2=0.52liters
6)v1=130,v2=85, t1=2500, t2=?
t2=(85×2500)/130
t2=212500/130
t2= 1634.6°c
Answer:
4046atm
Explanation:
For this question you can use the ideal gas law,
<em /><em />
Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.
Because of the units given, R will equal .08026
Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):
This will give you:
