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.
Because lager objects have much more room for mass the smaller objects. take the earth as an example the earth is very big and has alot of mass in it which makes gravity that pulls us down when we jump up.
Answer:
W and X
Explanation:
isotopes : are masses of atoms with the same number of proton and electron but different neutron .
W and X have the same number of protons and different number of neutrons.
H₃PO₄ + H₂O:
H₃PO4 + H₂O --> 3 H₃O⁺ + PO₄³⁻
