Answer:
1dm = 10cm
1dm3 = 10cm x 10cm x 10cm = 1000cm3
1L = 1000cm3
so 1litre = 1dm3
4 moles in 2 dm3
= 2 moles in 1dm3 = 2moles in 1L = 2M
1L = 1000cm
0.3 moles in 200cm3 =
200cm3 = 0.2L
so 0.3 moles in 0.2 L = 1.5 moles in 1 L = 1.5M
(I have tried to simplify and show why 1dm3 = 1L)
I hope this helps you understand!
Ideal gas is defined as hypothetical gas that fits all the assumptions of the kinetic-molecular theory. There are several assumption statement that apply to the behavior of an ideal gas, First Gases consist of larger number of tiny particles that are far apart relative to their size, Second, collisions between gas particles and between particles and container walls are elastic collision, third, gas particles are in rapid, random motion and continuous, Fourth, the temperature of a gas depends on the average kinetic energy of the particles of the gas.
It depends if your talking about science or math but It could be both if it says something about weathering which is what causes a rock to break it might be chemical ill comment and tell you the correct answer
the answer would be equal to 0.253 mol
4.42
Because when you divide 129/29.20, you get a long string of numbers. 4.417808219178082...
So you round to the significant figure which in this case is 2 decimal places because 29.20 has 2 decimal places.
PS did you draw that car? Cuz im into drawing cars too.
