<span>Molarity
is expressed as the number of moles of solute per volume of the solution. We solve the problem above as follows:
0.1000 mol Mg(NO3)2 / L (.1 L) ( </span><span>148.3 g / mol ) = 1.483 g Mg(NO3)2
</span>0.1000 mol Sr(NO3)2 / L (.1 L) ( 211.63 g / mol ) = 2.116 g Sr(NO3)2
Hope this answers the question. Have a nice day.
Answer:
Mass of the water = 0.1kg is 100g
Explanation:
Mathematically;
Quantity of heat = mass of water * specific heat capacity * temperature change
From the question, we identify the following;
Quantity of heat = 6.3 KJ
1 KJ = 1000 J, so 6.3 KJ = 6.3 * 1000 = 6300 J
Mass of water = ?
Specific heat capacity = 4200
Temperature change is the difference between the final and initial temperature. = 75-60 = 15
6300 = m * 15 * 4200
63 = m * 15 * 42
63 = 630 m
m = 63/630
m = 0.1 kg
Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution
There are O-H bonds in H2O. They have the intramolecular force of polar covalent bond.
In a balloon there is a low pressure within the balloon. This means that the particles are more spaced out. Wheras in the cylinder they are under high pressure, meaning that the particles are much closer together!
