<span>23.8 g/mol
Since the definition of molar mass is mass per mole, just divide the mass of the sample by the number of moles you have. So
0.250 g / 1.05x10^-2 mol = 23.8095 g/mol
Since our input data only has 3 significant figures, you need to round the result to 3 significant figures.
23.8095 g/mol rounds to 23.8 g/mol</span>
Democritus and Aristotle had argued in the study of atoms as

only agreed on is that the atoms are made of large numbers and these atoms have
different types.

B
Explanation:
If the concentration is increased, there are more particles to collide with each other, increasing the rate of the reaction.
Answer:
Polarity in chemistry referred to physical properties of compounds related to solubility, melting and boiling properties.
Polarity of black pepper can be seen when black pepper is sprinkled on water. The balck pepper float on water and get displaced if touched.
It means black pepper is non-polar and have no difference in electronegativity between bonded atoms. Black pepper is so light in weight and non-polar, the surface tension of water keep it floating in the water.

i am pretty sure the answer is a
Explanation: because the airplane's flight time has to be the independent variable for it to affect the dependent variable that is the speed of how fast the airplane is going.
