Answer: the momentum is 6 Kgm/s
Explanation:
M= 5 kg
V= 1.2 m/s
Momentum = MV = 5 x 1.2 = 6 Kgm/s
Answer:
number of moles of
=4.16mol
Explanation:
experiment data:
temperature=
=273+22 k=295k
pressure=1.007 atm
volume is missing so assuming volume-=100L
using ideal law relationship
ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.
PV=nRT
put all the experimental data, we get
n=4.15 mol
number of moles of
=4.16mol
The empirical formula or simplest formula
gives the smallest whole-number ratio of
the atoms present in a compound.It gives the
relative number of atoms of each
element present in the compound.The ratio will be 3.72 : 21.28
