Answer:
A
Explanation:
1g=1000mg
1g= 1000 000 micro gram
1g= 1000 000 000 nm = 10^9
Answer:
- 7.48
Explanation:
Given:
Concentration of the sugar solution, C = 0.3 M
Temperature, T = 27° C = 273 + 27 = 300 K
Now,
The solute potential is given as:
solute potential = - iCRT
where,
i is the number of particles the particular molecule will make in water
i = 1 for sugar
R is the universal gas constant = 0.0831 liter bar/mole-K
on substituting the respective values, we get
solute potential = - 1 × 0.3 × 0.0831 × 300
or
The solute potential = - 7.479 ≈ - 7.48
Answer:
The density is 2.5625g/mL. Hope this helped! :)
Explanation:
M= 8.2g D=M/V
V= 28.3-25.1=3.2mL
D=8.2g/3.2mL
D= 2.5625g/mL
