Answer and Explanation:
The molar mass of a substance is all of the weights from the elements combined.
So, we have the elements
CU, S, and 
CU has a mass is 65
S mass is 32
O has a mass of 16, but there's 4 atoms of O, so we do 16 times 4, which is 64.
Now we add.
65 + 32 + 64 is 161.
<u>So, the answer is 160, or answer choice A.</u>

Answer:
Percent composition tells you which types of atoms (elements) are present in a molecule and their levels. Percent composition can also tell you about the different elements present in an ionic compound as well.
Answer:
The answer is B.
Explanation:
They are the strongest type of inter-molecular force attractive forces that can act between atoms. This is why Vander Walls forces important.
Molar mass:
KOH = 56.0 g/mol
Number of moles of KOH :
5.93 / 36.5 => 0.1624 moles
<span>KOH + HCl = KCl + H₂O
</span>
1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?
moles HCl = 0.1624 x 1 / 1
= 0.1624 moles of HCl
V ( HCl ) = moles / molarity
V(HCl) = 0.1624 / 0.183
V (HCl) = 0.887 L x 1000 = 887 mL
hope this helps!
Answer:
The major ionic constituents whose concentrations can be determined from the salinity are known as conservative substances. Their constant relative concentrations are due to the large amounts of these species in the oceans in comparison t
