Answer:
0.71
Explanation:
The molecular mass of NaCl is, 23+35.5
= 58.5
1 mole means molecular mass (in gram)
In 58.5 gm NaCl there is 1 mole.
So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.
Answer:
No it will not
Explanation:
It will not float because the density is 1.21903052065, it needs to be less than 1 to float
Answer:
Higher fluid resistance
Explanation:
Because the fluid become compressible the fluid resistance increase
