Answer:
11.2 M
Explanation:
Given data:
Number of moles = 6.7 mol
Volume of solution = 0.6 L
Concentration /Molarity = ?
Solution:
Molarity:
It is number of moles of solute in to per kg or litters of solution. It can be calculated by the following formula.
Molarity = number of moles / Volume in L
Now we will put the values in formula.
Molarity = 6.7 mol / 0.6 L
Molarity = 11.2 mol/L
Molarity = 11.2 M
Explanation:
As density is defined as the mass of a substance divided by its volume.
Mathematically, Density = 
It is given that mass is 50 g and density is 0.934
.
Hence, calculate the volume of methyl acetate as follows.
Density = 
0.934
= 
Volume = 
or, =
(as 1
= 1 mL)
Thus, we can conclude that the volume of methyl acetate the student should pour out is
.
Answer:
D to absorbe energy from the sun's radiation to heat wats
To determine strength of attractive forces between the molecules the size of the molecules, their polarity (dipole moment), and their shape. ... If two molecules have about the same size and similar shape, the dipole-dipole intermolecular attractive force increases with increasing polarity.
The answer is (C) as the definitions states that atomic mass is the number of protons and neutrons.
Hope this helps :).
