Answer:
3) Density multiplied by volume
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
So by rearranging this formula mass can be determine.
d = m/v
m = d×/v
Unit of mass when volume in mL and ddensity is g/mL
m = g/mL×mL
m = g
Example:
density = 5g/mL
volume = 3 mL
mass = ?
m = d×v
m = 5g/mL ×3 mL
m = 15 g
A substance that has no specific volume changes to a substance that has a specific volume.
When waves act together, you talk about "interference".
When they reinforce each other, it is "constructive interference".
When they cancel each other, it is "destructive interference".
Answer:
0.6522 mol/L.
Explanation:
<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>
<em />
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (no. of moles of solute)/(V of the solution (L)) </em>= (1.5 mol)/(2.3 L) = <em>0.6522 mol/L.</em>
