Answer:
The answer to your question is below
Explanation:
1) 0.143g of Mg into atoms
- Look for the atomic number of Magnesium in the Periodic table
Atomic number = 24.31 g
-Use the Avogadro's number to find the number of atoms
24.31g ------------------- 6.023 x 10²³ atoms
0.143 g ----------------- x
x = (0.143 x 6.023 x 10²³) / 24.31
x = 8.613 x 10²² / 24.31
x = 3.54 x 10²¹ atoms
2) 0.101 kg of Ti into atoms
-Look for the atomic number of Titanium in the Periodic table
Atomic number = 47.87 g
-Use the Avogadro's number to find the number of atoms
47.87 g --------------------- 6.023 x 10²³
101 g ---------------------- x
x = (101 x 6.023 x 10²³) / 47.87
x = 6.08x 10²⁵ / 47.87
x = 1.27 x 10²⁴ atoms
Answer:

For each of the following changes of the initial balloon, select ... A sample of nitrogen (N2) has a volume of 60.0 L at a pressure of 725 mmHg.
Explanation:
1) Cellulose - extracellular location, glycosidic bond, β-linkage. Cellulose is polysaccharide composed of glucose linked with β-1,4 bons.
2) Messenger RNA - informational macromolecule, phosphodiester bridge, helical structure possible, synthesis requires a template. mRNA is nucleic acid, <span> mRNA is </span>translated<span> into a polymer of amino acids.</span><span>
3) </span>Globular protein - peptide bond, helical structure possible, synthesis requires a template. Protein is composed of amino acid linked with peptide bond, secundary structure can be α-helix, gene expression.<span>
4) </span>Amylopectin - branched-chain polymer, glycosidic bond, helical structure possible. Amylopectin is subunit of starch, sugar with α-1,4 and α-1,6 glycosidic bonds.<span>
5) DNA - i</span>nformational macromolecule, phosphodiester bridge, helical structure possible, synthesis requires a template, nucleoside triphosphate. DNA is helical <span>chain of </span>nucleotides<span> carrying the </span>genetic<span> instructions.</span>
6) Fibrous protein - peptide bond, helical structure possible. Protein is composed of amino acid linked with peptide bond
Mole is equal to mass of the element divided by molar mass of the element. that is
mole=mass/molar mass
From periodic table calcium has a molar mass of 40 g/mol
moles is therefore =800g/40g/mol=20moles
