To explore the use of punnett square to predict genotype and phenotypes of offsprings an investigation must be conducted
5 grams of sodium polyacrylate
Answer:
Number of moles = 0.05 mol
Explanation:
Given data:
Mass of Pb = 10.5 g
Number of moles of Pb = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of Pb is 207.2 g/mol.
Now we will put the values in formula.
Number of moles = 10.5 g/207.2 g/mol
Number of moles = 0.05 mol

7f 7 3 7+3 = 10
5d 5 2 5+2 = 7
3s 3 0 3 + 0 = 3
6p 6 1 6 + 1 = 7
4f 4 3 4 + 3 = 7
6d 6 2 6 + 2 = 8
The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
