Answer:
393.1 KPa
Explanation:
Now we have to use the general gas equation;
P1V1/T1 = P2V2/T2
P1= initial pressure of the gas= 1.00atm
V1 = initial volume= 700.0 ml
T1= initial temperature= 0.0°C +273= 273K
V2= final volume= 200.0 ml
T2= final temperature =30.0°C +273= 303 K
P2= final pressure =????
Therefore;
P2= P1V1T2/ V2T1
P2= 1.00 × 700.0 × 303/ 200.0 × 273
P2= 3.88 atm
But
1 atm = 101.325 kilopascals
Therefore 3.88 atm = 3.88 × 101.325 kilopascals = 393.1 KPa
Answer:
their density is only lighter than water because of the air inside. without the air you would sink even if you were holding it firmly.
Explanation:
Answer:
a. 0.0855 M
b. 0.153 M
c. 0.0351 M
d. 0.0901 M
Explanation:
a.
Molar mass NaCL= 23.0 +35.5 = 58.5 g/mol
10.0 g* 1 mol/58.5 g = 10.0/58.5 mol
(10.0/58.5) mol/2L = 0.0855 mol/L = 0.0855 M
b.
Molar mass (C12H22O11) =342.3 g/mol
52.5 g*1mol/342.3 g = 52.5/342.3 mol=0.153 mol
0.153 mol/1L = 0.153 M
c.
Molar mass (Al2(SO4)3) =342.2 g/mol
120g* 1 mol/342.2 g =0.351 mol
0.351 mol/10.0L = 0.0351 mol/L = 0.0351 M
d.
Molar mass (C8H10N4O2) = 194.2 g/mol
1.75 g*1mol/194.2 g = 0.00901 mol
0.00901 mol/0.100 L =0.0901 M
Solid= Connected and Concentrated and Bound Together.
Liquid= Not bound but free flowing, less concentrated.
Gas= Spaced out and not concentrated, floating freely through space.
