Collision with a high-speed particle
<u>Answer:</u> The mass of water that should be added in 203.07 grams
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
m = molality of barium iodide solution = 0.175 m
= Given mass of solute (barium iodide) = 13.9 g
= Molar mass of solute (barium iodide) = 391.14 g/mol
= Mass of solvent (water) = ? g
Putting values in above equation, we get:
Hence, the mass of water that should be added in 203.07 grams
(d) Density of Benzene: 0.8786 g/cm cubed
(m) Mass: 20.00g
Formula to solve (v) volume of benzene: V=m/d
V=20g / 0.8786g/cm cubed
Answer: Volume of benzene is: 22.8 cm cubed
Explanation: Well, density is mass divided volume. In this, it is what the volume is. All you need is mass divided by density. Hope this helps!
Compound A : SnCl2
the mass ratio of Cl and Sn: 71 g Cl/ 119 g Sn = 0.579 g Cl/ 1 g Sn
Compound B: the ratio of mass of chlorine per 1 g Sn is twice the ratio of chlorine per 1 g Sn in compound A => 1,194 g Cl/ 1 g Sn = 142,086 g Cl/ 119 g Sn
=> the number of chlorine/ 1 atom Sn = 142.086/ 35.5 = 4.
=> the formula of B: SnCl4
