Use equation density = mass/volume
Known/Given
d= 10.5g/cm^3
v= 24.0 cm^3
Use that equation i just mentioned...
Solution
Rewrite the formula as the forumla for solving density into mass
Which is... mass = 10.5g/cm^3 × 24.0cm^3 = 252g
So thats the answer
252g
Hope i could help
Answer: second answer
Explanation:
The thing is that every new nuclear cycle a new element forms and reduces an electron. I may be wrong but this is the most logical and scientifically correct answer
Multiply the mass by the abundance and add each. Make sure to convert the percentage into a decimal. (49.946 * .043) + (51.941 * .838) + (52.941 * .095) + (53.939 * .024) = 51.99 round up using sig figs and the answer is c. 52.00 amu
So they can tell what exact species it is.
Aluminum is an element. If there's nothing else in the foil
besides aluminum, then the foil is entirely an element.
