Answer:
1500kg/m^3
Explanation:
Formula:
d=m/v
Given:
m=1.5kg
v=1000cm^3
(The side length of a cube is always equal to the others)
Required:
d=?
Solution:
d=m/v
d=1.5kg/1000cm^3
d=1.5kg/0.001m^3
d=1500kg/m^3
Hope this helps ;) ❤❤❤

Option B is true , the same number of moles of solute in both solution is the same.
<h3>What is Molarity? </h3>
Molarity is the ratio of no of moles as per liter solution. It is denoted by M and SI unit is also M or moles/litre.
Molarity = no . Of moles/Volume (L)
In this question the amount of solution is increased means the volume is increased from 500-700ml it is increased , Molarity is inversly proportional of Volume
it will decrease if volume increase. Adding water do affect the concentration of the solution. The no. Of moles of solute remains because there no increament in amount of NaCl .
Hence ,option B is more correct
