Question

7. If the density if ethanol (C2H5OH) is 0.888 kgL-1, what is its volume needed for making 1.15L of its 0.75M?

Answer 1

Answer:

Explanation:

moles=molarity*volume

moles=3/4*1.15 = 0.8625

moles=0.8625

mass=0.8625*46 = 39.675 gm

mass=density*volume

39.675/888 = volume

0.044 ml = volume
