N=1.2·10²⁴
Nₐ=6.0221·10²³ mol⁻¹
n₂(H₂O)=4 mol
n₁(H₂O)=N/Nₐ
n=n₁+n₂=N/Nₐ+n₂
n=1.2·10²⁴/6.0221·10²³ + 4 = 5.99 mol
5.99 <span>moles of water are in the glass</span>
Answer: Option (A) is the correct answer.

hopefully this helped :3
<span>Heavy metals like mercury enter waterways by industrial dumping and poor regulatioin of effluent, and they also enter soil through a similar manner, in which waste is disposed of imporperly. Another source of heavy metals are the gases leaving industry carrying these metals. The metals fall as a solid on to soil and water ways. Therefore, the answer is D.</span>
