What is the percent by mass of water in Na2SO4 • 10H2O?
bulgar [2K]
We determine the percent by mass of water in the compound by dividing the mass of  water by the total mass. The total mass of Na2SO4.10H2O is equal to 322 g. The mass of water is 180 g. 
       
                    percent by mass of water = (180 / 322)*(100 %) = 55.9%

Answer:

Option A.

Lower air pressure results in a lower boiling point

Explanation:

This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid

But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.

a 3.0 M solution of HCl can be prepared from a 12.0 M solution by diluting 30 L of the 12.0 M solution ith suffient distilled wa
Alex_Xolod [135]
<h3>Answer:</h3>

Final volume is 120 L

<h3>Explanation:</h3>
  • Using the dilution concept, dilution involves adding more solvent to a concentrated solution to make it dilute. This results to a dilute solution with less solute concentration and more solvent.

According to the dilution equation;

M1V1 = M2V2

Where, M1 is the molarity  and V1 is the volume of the concentrated solution, while M2 and V2 are the molarity and volume of the diluted solution respectively.

In this case;

M1 = 12.0 M

V1 = 30 L

M2 = 3.0 M

V2 = ?

Therefore;

V2 = M1V1 ÷ M2

    = (12 × 30) ÷ 3

   = 120 L

Hence, the final volume will be 120 liters
