The molar mass of the sample is equal to the summation of the molar mass of the elementas multiplied by the abundance of the elements by mole. In this case, copper has an abundance of 93.69 percent while zinc has 6.31 percent. In this case, the average molecular weight is 63.67 g/mol
Answer:
Average density of Sun is 1.3927 .
Given:
Radius of Sun = 7.001 × km = 7.001 × cm
Mass of Sun = 2 × kg = 2 × g
To find:
Average density of Sun = ?
Formula used:
Density of Sun =
Solution:
Density of Sun is given by,
Density of Sun =
Volume of Sun =
Volume of Sun =
Volume of Sun = 1.436 ×
Density of Sun =
Density of Sun = 1.3927
Thus, Average density of Sun is 1.3927 .
Answer:
