Answer:
1.1 × 10² g
Explanation:
First, we will convert 1.0 L to cubic centimeters.
1.0 L × (10³ mL/1 L) × (1 cm³/ 1 mL) = 1.0 × 10³ cm³
The density of water is 1.0 g/cm³. The mass corresponding to 1.0 × 10³ cm³ is:
1.0 × 10³ cm³ × (1.0 g/cm³) = 1.0 × 10³ g
1 mole of water (H₂O) has a mass of 18 g, consisting of 2 g of H and 16 g of O. The mass of Hydrogen in 1.0 × 10³ g of water is:
1.0 × 10³ g H₂O × (2 g H/18 g H₂O) = 1.1 × 10² g
The first one would be the best answer
Based on concentration of solute particles and hence the osmotic pressure the solutions can be classified into three categories , with respect to other solutions
a) isotonic: when concentration of one of the solution is same as of the other solution then they are referred as isotonic to each other.
b) hypertonic: When concentration of the solution is greater than the concentration of other solution then it is said to be hypertonic.
c) hypotonic: when concentration of the solution is lesser than the concentration of other solution then it is said to be hypotonic.
So a solution with high concentration of solute will have higher osomotic pressure and will called to have high pressure or tone hence called as hypertonic.
Thus compartment A will have high concentration and will called as hypertonic while the compartment B will have low concentration and will called as hypotonic
Answer:
3.24 mol/L
Explanation:
Given that:
mass of Boron triiodide = 6664 grams
molar mass of BI_3 = 391.52 g/mol
Recall that:
number of moles = mass/molar mass
∴
number of moles = 6664 g /391.52 g/mol
number of moles = 17.02 mol
Also;
Molarity = moles for solute/liter for solution
= 17.02 mol/5.25 L
= 3.24 mol/L
