Answer:
Mole fraction of
= 0.58
Mole fraction of
= 0.42
Explanation:
Let the mass of
and
= x g
Molar mass of
= 33.035 g/mol
The formula for the calculation of moles is shown below:
Thus,
Molar mass of
= 46.07 g/mol
Thus,
So, according to definition of mole fraction:

Mole fraction of
= 1 - 0.58 = 0.42
Answer:
0.0008 m
Explanation:
We are given that 0.080 cm
We have to convert 0.080 cm into meter
To find the value of 0.080 cm in meter we are using unitary method
We know that
100 cm =1 m
1 cm =
Therefore, 0.080 cm =
0.080 cm =
0.080 cm =
0.08cm=0.0008 m
Hence, the value of 0.080 cm is equal to 0.0008 meter .
