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:
a. NaNO3 and CuCl2
Explanation:
The other 3 react as follows:
Ba(OH)2 and HNO3 ---> BaNO3 + H2O
CaCl2 + Na3PO4 ---> CaPO4 + NaCl
AgNO3 + HCl ---> AgCl + HNO3
Low melting point
Low boiling point
Electric conductor
Answer:
Newton's laws are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or sit still, like why you don't float out of bed or fall through the floor of your house.
Explanation: Newton's laws of motion are important because they are the foundation of classical mechanics, one of the main branches of physics. Mechanics is the study of how objects move or do not move when forces act upon them.
There are 0.400 mol Br₂ in the sample..
Mass of Br₂ = 20.5 mL Br₂ × 3.12 g Br₂/1 mL Br₂ = 63.96 g Br₂.
Moles of Br₂ = 63.96 g Br₂ × (1 mol Br₂/159.81 mol Br₂) = 0.400 mol Br₂
