Answer:
2.209g/mL
Explanation:
The density of a substance is defined as the ratio between its mass (Generally in grams) and its volume (Generally in mililiters).
The volume dispensed in a buret is: Final volume - Initial volume. In the problem:
45.91mL - 35.00mL = <em>10.91mL</em>
As the mass of solution dispensed is <em>24.10g</em>, density is:
24.10g / 10.91mL = <em>2.209g/mL</em>
I hope it helps!
Answer: 3.42 L
Explanation:
Molarity equation = moles / L
.35 M = 1.2 mol / L
volume = 3.42 L
All of those quantities contain the same number of particles, since they are all two moles (or 1.204*10^24 particles).
It's similar to asking which one is heavier: a pound of brick, or a pound of feathers. Since they are both one pound, they will weigh the same.
Hope that helped! :)
Do you mean cm^3?
The density of gold is 19.32 grams / cm^3
d = mass / volume
19.32 = mass/ 4.58 cm^3
19.32 * 4.58 = 88.5 grams
