Answer:
are those the answer choice
Answer : The mass in grams of calcium sulfate is 0.16 grams.
Explanation :
Molarity : It is defined as the number of moles of solute present in one litre of solution.
Formula used :
Solute is, 
Given:
Molarity of = 0.0025 mol/L
Molar mass of = 136 g/mole
Volume of solution = 485 mL
Now put all the given values in the above formula, we get:
Thus, the mass in grams of calcium sulfate is 0.16 grams.
Volume= mass divided by density
V= m/d
55/3.23
= 17.03
The net force is the sum of all of the forces that cancelled out to zero. Hence, option D is correct.
<h3>What is force?</h3>
The pushes or pulls on an object with mass causes it to change its velocity.
The net force is the vector sum of all forces acting on an object. Force is a vector quantity.
Two forces of equal magnitude when acting on an object in opposite directions will cancel out each other.
As a result net force is equal to 0. The word net here shows the total force acting on the object.
Hence, option D is correct.
