Explanation:
Answer:
19) 3.6920 × 10⁻⁵
20) 4.059× 10²
21) 2.46810121416 × 10³
22) 1.0000× 10⁻³
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.000036920
In scientific notation = 3.6920 × 10⁻⁵
405.9
In scientific notation = 4.059× 10²
2468.10121416
In scientific notation = 2.46810121416 × 10³
0.0010000
In scientific notation = 1.0000× 10⁻³
Answer:
about 79% (79.04369332 to be exact)
Explanation:
Percent composition=(Molar mass of element x amount of it)/Molar mass of compound x 100
Br= 3 x 79.9/303.25 x100=79.04369332
