density = mass /volume
1)mass of rock = 26.0 gram
2)volume of rock = volume of water it has displaced= 25.3-13.12 = 12.18
put the value of mass and volume in first equation and get the density value
Answer:
atomic number
Explanation:
atomic number is the number of protons
The way to working out the numbers is to increase the measure of HNO3 required by the molarity to discover what number of moles you require: 0.115. You ought to have the capacity to make sense of the recipe weight H is 1, N is 14, O is 16. The result of the quantity of moles duplicated by the recipe weight ought to give an esteem in grams. You can utilize the thickness to change over to a volume of HNO3 to add to the right volume of water.
