0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.
Define the molarity of a solution.
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Volume of solution = 911 mL=0.911L
Given the mass of MgS = 29.9 g
Molar mass of MgS = 56.38 g/mol
Moles of MgS = 0.5303299042
Molality = 0.5821403998=0.58
Hence, 0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.

Answer:
It lets people prepare for future weather hazards:
- If, in certain months and on certain dates, the past data shows that there's a history of rain or heat stroke on those days, people can prepare in the future for those events.
- They can also expect wind speeds, temperatures and stuff like that!
Converting the specific heat into kJ/kg°C, we get that the specific heat capacity is 3.52 kJ/kg°C
Now, we use the equation:
Q = mcΔT, where Q is the heat energy, m is the mass of substance, c is the specific heat capacity and ΔT is the change in temperature of the mass of substance. Substituting these values, we get:
Q = 1.4 x 3.52 x (27.45 - 28.5)
Q = -5.17 kJ
The reaction absorbs 5.17 kilojoules of energy.
Answer:
Component P, because being supported by ample evidence is a characteristic of a theory.
Explanation:
Hypothesis do not explain phenomenon they are just educated guesses that can be put into work to see if they are true of false.
Scientific theory on other hand, is widely accepted and supported by large amount of evidence and useful for explaining scientific phenomenon.
