I believe that the ice cube, being that it still has almost all of its properties, would still have a mass of 25 g after melting
Answer:
<h2>1.686 × 10²⁴ atoms</h2>
Explanation:
The number of silicon atoms can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2.8 × 6.02 × 10²³
We have the final answer as
<h3>1.686 × 10²⁴ silicon atoms</h3>
Hope this helps you
option of d is the write answer
Answer:
<h2>10 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2 × 5
We have the final answer as
<h3>10 g</h3>
Hope this helps you
The answer to this question is 2 and 3
