Density of liquid= 
.
so, density of liquid= 
= 1.2 gm/cm³.
The concentration of a cell is generally 0.15 M (0.9 % NaCl)
As given the solution has concentration = 200mm = 0.02 M
This concentration of solution is less than the concentration of cell
Hence solution is hypotonic (less concentration) and cell will be hypertonic
Answer:
The answer is <u>C. As2O3</u>
Explanation:
0.600 gr of Arsenic and Oxygen.
0.454 gr of Arsenic
So, 0.146 gr of Oxygen will be in the compound.
- First: The grams of each element must be divided by its atomic weight:
- 0.454 gr As / 74.92u As = 0.00606
- 0.146 gr O / 16u O = 0.009125
- Both results must be divided by the lowest number found:
- 0.009125 / 0.00606 = 1.5 O
- As one of the values is not an integer then both results are multiplied until both give an integer:
- Then the answer is given:
