Answer:
2.03
Explanation:
Let's <u>assume we have 1 L of the solution</u>:
- There would be 2.07 ethylene glycol moles.
- The solution would weigh (1000 mL * 1.02 g/mL) = 1020 g.
With that information we can <u>calculate the molality</u>:
- molality = moles of solute / kg of solvent
- molality = 2.07 moles / (1020 ÷ 1000) = 2.03 m
Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.
Mass was conserved, because it was losing all shape, weight, and matter. It really has no mass.
Answer:
Cause/ effect relationship.
Explanation:
because the force is the cause of energy that is present and velocity is the effect (speed) that is present.
Answer:
B
Explanation:
Vanadium Oxide is a Catalyst for the contact process
And Catalysts are used to speed up the reaction rate, therefore the answer is "to increase the rate if reaction"
SIDE NOTE = catalysts are not used up in a reaction btw
Answer:
0.0522 mol NaSo4
Explanation:
3.148 x 10^22 Formula units NaSo4 * 1 mol NaSo4 / 6.02 x 10^23 Formula units NaSo4 = 0.0522 mol NaSo4
