The organs in the alimentary canal are important to digestion because they work together to move food and waste through the body. Without them, food wouldn't be able to move to their correct organs to digest and provide nutrients & energy, and waste would not be able to get out of the body.
B. Has natural predators to limit population
1,100 grams :)
you add the grams of both substances and because they're liquid they don't cancel out
Answer:
3.2043 x 10²³
Explanation:
No. of Mole of lead (Pb) = 0.532 mol
No. of atoms of lead = ?
Solution:
Formula Used to calculate
no. of moles = numbers of particles (ions, molecules, atoms) /Avogadro's number
Avogadro's no. = 6.023 x10²³
So,
The formula could be written as
no. of atoms of lead Pb = no. of moles x 6.023 x10²³
Put the values in above formula
no. of atoms of lead Pb = 0.532 mol x 6.023 x10²³
no. of atoms of lead Pb = 3.2043 x 10²³
so 3.2043 x 10²³ atoms of lead are contained in 0.532 mole.
