Answer:
What does ppm mean? This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.
that is all i have to say.
Isn't that a substitution reaction? Sorry if i am wrong haven't taken these in a while
Hey there!:
Molar mass NaOH = 39.997 g/mol
Number of moles ( solute )
n = mass / molar mass
n = 1.00 / 39.997
n = 0.0250 moles of NaOH
Volume in liters:
500.0 mL / 1000 => 0.5 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.0250 / 0.5
Molarity = 0.05 M
Hope that helps!
2.3*10^-2 M/s IS THE ANWSER<span>
