The molarity of the solution is 0.1625M.
<h3>What do you meant by Molarity</h3>
Molarity is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of solute per litres of a solution .
Molarity → no of moles / Volume (L)
SI unit of Molarity is M or mol/ L
We have given here the mass of solution is 3.10×10²g .
molality of the solution is 0.125m
Molality → no of moles / mass in kg
→ 0.125×3.10×10²/ 1000
→ no.of moles = 0.0162
For molarity we can assume volume as 1000 ml .
Molarity = 0.0162×1000/ 100
Molarity →0.162 M.
So, the molarity of solution will be 0.162M.

Answer:
53.1 mL
Explanation:
Let's assume an ideal gas, and at the Standard Temperature and Pressure are equal to 273 K and 101.325 kPa.
For the ideal gas law:
P1*V1/T1 = P2*V2/T2
Where P is the pressure, V is the volume, T is temperature, 1 is the initial state and 2 the final state.
At the eudiometer, there is a mixture between the gas and the water vapor, thus, the total pressure is the sum of the partial pressure of the components. The pressure of the gas is:
P1 = 92.5 - 2.8 = 89.7 kPa
T1 = 23°C + 273 = 296 K
89.7*65/296 = 101.325*V2/273
101.325V2 = 5377.45
V2 = 53.1 mL
Answer:
1 gram of H2 will be produced from 12 grams of Mg.
Explanation:
According to Stoichiometry, 0.5 moles of Mg are present. 1 mole of Mg produces 1 mole of H2, so 0.5 moles of Mg will produce 0.5 moles of H2. Multiplying molar mass of H2 i.e. 2 gram/mole with 0.5 moles, we can find the mass of H2 in grams which is 1 gram.
