Answer:
Molarity = 0.08 M
Explanation:
Given data:
Mass of sodium carbonate = 10.6 g
Volume of water = 1.25 L
Molarity of solution = ?
Solution:
First of all we will calculate the moles of solute.
Number of moles = mass/molar mass
Number of moles = 10.6 g/ 106 g/mol
Number of moles = 0.1 mol
Formula:
Molarity = moles of solute / volume of solution in L
Now we will put the values in formula.
Molarity = 0.1 mol / 1.25 L
Molarity = 0.08 M
Answer:
the water.
Explanation:
well the water makes things look larger than due to ( the surface of a water drop curves outwards to make a dome. this outward or convex, curature light rays inward. the result is an enlarge ment image on the eye. / makes it look larger) + more mass.
<span>Actually, the heat of reaction hrxn s calculated by taking
the sum of the heats of formation of the products minus the sum of the heats of
formation of the reactants. However, at heat of formations of pure elements at
atmospheric conditions is zero, therefore the hf of N2 is not important since
it is zero anyway.</span>
They are about 4.5 billion years old. Hope this helps.
Answer: hey so I’m taking the same test as you right now. I’m on that question and I searched it up and came on here. Would you mind telling me the answer?
