First, determine how many moles of NaCl you have
Atomic weight sodium = 22.989769
Atomic weight chlorine = 35.453
Molar mass NaCl = 22.989769 + 35.453 = 58.442769 g/mol
Moles NaCl = 15.4 g / 58.442769 g/mol = 0.263505653 mol
Now molarity is defined as moles/liter, so let's set up an equation for the number of liters we can make.
molarity = moles/liter
Substitute the known values
5.00 = 0.263505653/liter
And solve for liters
5.00 = 0.263505653/liter
5.00* liter = 0.263505653
liter = 0.263505653/5.00
liter = 0.052701131
So you can make 0.0527 liters of the solution. Or 52.7 ml</span>
Answer:
Animals gain energy from the food they eat. Some animals eat plants while others eat other animals. This is passing of energy from the sun to plants to animal to other animals is called a food chain

Answer: pure substances.
Explanation:
The given substances are:
All what surrounds us, which has mass and occupies spaces, is matter. There are two kind of matter: pure substances and mixtures.
Pure substances have a uniform and constant composition. On the other hand, mixtures are combinations of two or more pure substances in any arbitratry ratio.
Pure substances may be elements or compounds. The elements are the substances conmposed by one only kind of atom. In the list of substances given, Li and O₂ are elements: all the atoms in Li are lithium, and all the atoms in O₂ are oxygen atoms.
Compounds are the chemical combination of two or more different kind of atoms. In the given list H₂O₂ and NaCl are compounds. As you see, H₂O₂ contains atoms of hydrogen and oxygen, chemically bonded, in a fixed ratio (2 atoms of hydrogen by 2 atoms of oxygen). And NaCl has atoms of Na (sodium) and Cl (chlorine), chemicaly bonded, in a fixed ratio (1:1).
There are only 118 known elements and you can find them in any modern periodic table. Therer are virtually infinitely many compounds since many different combinations of the elements can be attained.
Elements and compounds have in common that they are classified as pure substances.
