2. Density is expressed as the ratio between the mass and the volume of a substance so:

Solving for m:

3. Replace values:


They have less or more neutrons. Isotopes have same number of protons but different number of neutrons.
The coefficient for sulfuric acid wen reaction between calcium phosphate and phosphoric acid occurs is
three (3)
<h2>explanation</h2>
write a balanced chemical equation for the reaction
that is
Ca3(PO4)2 + 3 H2SO4 →2 H3PO4 + 3CaSO4
since coefficient is number in front of a chemical formula the coefficient of H2SO4 is 3
