Answer:
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
Explanation:
To convert grams to moles, we need the molar mass of carbon. this can be founded in the periodic table.
molar mass of C= 12.0 g/mol
38.1 g C (1 mol C/ 12.0 grams)= 3.18 moles of C
Answer:
79.994g NaOH
Explanation:
The formula for molarity is M=moles of solute/Liters of solution, M=n/L
You are given L and M, so 0.4=n/5
n (moles of solute) = 2
2 moles of NaOH, multiplied by the molar mass of NaOH (39.997) to get the mass needed: 79.994g
