Sagot :
The mass of Sodium hydroxide which is needed to make 2.500 L of a 2.000 M NaOH solution is 200 grams.
How do we calculate mass from moles?
Mass of any substance will be calculated by using their moles as:
n = W/M, where
W = required mass
M = molar mass
Given that, molarity of NaOH = 2M
Volume of NaOH solution = 2.5L
Moles of NaOH will be calculated by using the below equation as:
M = n/V
n = (2)(2.5) = 5 moles
Now we calculate the mass of NaOH of 5 moles as:
W = (5mol)(40g/mol) = 200g
Hence option (4) is correct.
