The unit M means that mole/L, So first change the unit of solution volume to L which is 0.25 L. So the mole of solute is 2.5*0.25=0.625 mol.
We are asked to calculate the original pressure of the system.
Boyle's law states the relationship between pressure and volume of gases. It states that pressure of gas is inversely proportional to volume of gases at constant temperature.
P1V1 = P2V2
parameters for the first instance on the left side and parameters for the second instance are on the right side of the equation
P - original pressure
P x 365.2 mL = 241.3 Torr x 478.2 mL
P = 316.0 Torr
Answer:
= 152.40 g
Explanation:
The equation for the reaction is;
Cu(s) + AgNO3 → Ag(s) + Cu(NO3)2
Mass of silver nitrate = 320.0 g × 0.75
= 240.0 g
Molar mass of silver nitrate = 169.87 g/mol
Therefore;
Moles of silver nitrate = 240.0 g/169.87 g/mol
= 1.413 moles
Mole ratio of Silver nitrate to silver metal = 1 : 1
Therefore, moles of silver metal = 1.413 moles
Hence;
Mass of silver metal = 1.413 moles × 107.868 g/mol
<u>= 152.40 g</u>
Answer:
A <u>mixture</u> is a material produced by mixing two or more distinct components in such a manner that there is no chemical response. Every component of purity is a <u>substance</u>. Every pure compound is a <u>substance</u>.
