Answer:

Explanation:
1. Moles of CCl₄

2. Molar mass of CCl₄
MM = 1 × 12.01 + 4 × 35.5 = 12.01 + 142 = 154.0 g/mol
3. Mass of CCl₄

4. Volume of CCl₄

The balanced chemical reaction is written as:
<span>NaOH + HCl → NaCl + H2O
We are given the amount of sodium hydroxide to be used up in the reaction. This will be the starting point for the calculation.
2.75 x 10^-4 mol NaOH ( 1 mol H2O / 1 mol NaOH ) ( 18.02 g H2O / 1 mol H2O ) = 4.96 x 10^-3 g H2O</span>
Permafrost soil (gelisol) is b) fragile.
Answer:
1.16atm
Explanation:
We are going to derive the mass of ether from density
mass=density *volume
Also moles=mass/molecular mass
molar mass C2H5OC2H5 =74.12 g/mole
the density of ether is 0.7134 g/ml
mass C2H5OC2H5 = 5.30 ml x 0.7134 g/ml = 3.78 g
moles C2H5OC2H5 =3.78 g x 1 mole/74.12 g = 0.0509 moles
PV = nRT where P=?; n=0.0509 moles; V=6.50L; R=0.0821 Latm/Kmol; T=35ºC +273 = 308K
P = nRT/V = 0.0509)(0.0821)(308)/6.50
P = 0.198 atm (to 3 significant figures (this is the partial pressure of diethyl ether).
TOTAL PRESSURE
P1+p2+p3
= 0.198 atm + 0.750 atm + 0.207 atm =1.1550atm
1.16atm(3 significant figures)
