Answer:
B) Stainless steel
Explanation:
Homogeneous mixture -
It refers to the composition of various substance , which leads to a mixture of complete uniform composition , i.e. , the ratio of each and every component of the mixture is constant all over the mixture , is referred to as a homogeneous mixture.
For example ,
In the solution of sugar and water , where 1 tablespoon of sugar is dissolved in 100 mL of water ,
The ratio of sugar and water remains constant all over the mixture.
Hence, from the given options the homogeneous mixture is B) Stainless steel .
Answer: 2.3 moles
Explanation:
Recall that based on Avogadro's law, 1 mole of any substance has 6.02 x 10^23 atoms
So if 1 mole of Aluminum = 6.02 x 10^23 atoms
Then, Z moles = 1.4 x 10^24 atoms
To get the value of Z, we cross multiply:
1 mole x 1.4 x 10^24 atoms = Z x (6.02 x 10^23 atoms)
1.4 x 10^24 atoms = Z x (6.02 x 10^23)
Hence, Z = (1.4 x 10^24 atoms) ➗ (6.02 x 10^23 atoms)
Z =2.3 moles
Thus, there are 2.3 moles in 1.4 x 10^24 atoms of aluminum.
