The amount of a
substance can be converted into grams of that substance by using the molar
mass. It is a physical property of a substance which describes the mass per
mole of the substance. The molar mass of CH3OH is 32.04 g/ mol. Multiplying the
given amount of CH3OH with the molar mass will yield to the mass of the substance.
<span>9.09x10^24 molecules CH3OH ( 1 mol / 6.022x10^23 molecules) (32.04 g/mol) = 483.63 g CH3OH
Dividing the molar mass of N2O which is 44.08 g/mol to the given amount will yield to the number of moles.
0.183 g N2O / 44.08 g/ mol =0.0042 mol N2O</span>
Answer:1176
Explanation:
Number of male students: 2940*(60/100)=1764
So the number of female students would be:
2940-1764=1176
Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
Answer:
4. homogeneous; distillation
Explanation:
Gasoline and motor oil are chemically similar. They are both mixtures of non polar hydrocarbons containing carbon and hydrogen atoms. However, motor oil is much more viscous Motor Oil. Hence we can say that the mixture of gasoline and motor oil are homogeneous and they can be separated by distillation.
