Answer:
0.605 molal
Explanation:
molality is the amount of solute in a particular mass of solvent.
lets calculate the amount of benzene solute.
mass of benzene= 13.3g
molar mass of C6H6= 12*6 +1*6 =72+7=78g/mol
amount of benzene= mass/molar mass
=13.3/78
=0.1705mol
molality= amount of solute/mass of solvent in kg
mass of solvent=282g=0.282kg
molality = 0.1705/0.282
=0.605 molal
Answer:
Temperature does not affect the radioactive decay
Explanation:
because Temperature has no factor in radioactivity
Good Luck
Answer:
There are many effects of radiation to the human body. (if you watch the 100, you'll see what happens)
