Using ideal gas equation,
PV=nRT
P=199 kpa
V=4.67 L
T=30+273K= 303K
n= number of moles of gas
R=8.321 L·kPa·K-1·mol-1
So using ideal gas equation,
n=PV/RT
=199*4.67/8.321*303\
=0.37 mol
Answer:
Explanation:
Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms.These are called as alkanes. The general formula for these hydrocarbons is 
Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is 
and 
.
1. Propyne is 
and is an unsaturated hydrocarbon.
2. Methane is 
and is a saturated hydrocarbon
3. Nonane is 
is a saturated hydrocarbon.
4. Methyl is 
and is a saturated alkyl group.
Earthquakes are created when tectonic plates rub, push, or pass each other. Tsunamis are made by earthquakes on the sea floor.

I am pretty sure it will help you! Regards.
NH3 + H20 YIELDS NH4+ + OH-
So, the NH3 and the OH- are stoichiometrically equivalent.
So, we have 0.15M OH-
p OH = -log [OH-]
p OH = -log[0.15) = 0.824
pH = 14 - p OH
pH = 13.18
