Answer:
The volume of gold is 3.3 cm³.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m³.
Other units are given below,
g/cm³, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of gold = 63 g
Density of gold = 19.32 g/cm³
Volume of gold = ?
Solution:
d = m/v
v = m/d
v = 63 g/ 19.32 g/cm³
v = 3.3 cm³.
First, we want to convert 569 mL to L:
569 mL (L/1000 mL) =.569 L
Now, we can divide to find molarity:
7.0 mol/.569 L =12 M
Answer:
it's important so sound transmits through vribrating air particles for example earbuds have small speakers but powerful. The wide design helps with the outside noise cancelation and comfort for the ear. <thats for buds (this is for headphones >). Headphones have a little bigger speaker's and the cushions like the bigger earbud designs it noise cancels and give better comfort.
P.S headphones aren't that comfortable after long periods of time
