The given molarity of sodium hydroxide solution = 2.0 M
The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH
Converting 65 mL to L:
Calculating the moles of NaOH in the final solution:
Finding out the volume of 2.0 M solution taken to prepare the final solution:
Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.
Answer:
wool
Explanation:
this is because wool is used in manufacturing clothes and other materials for human use.
Answer:
Nominal scales embody the lowest level of measurement.
Explanation:
they embody the lowest level of measurement.
1.58 × 10^(-10) in
<em>Step 1</em>. Convert picometres to metres
4.01 pm × [10^(-12) pm]/[1 m] = 4.01 × 10^(-12) m
<em>Step 2</em>. Convert metres to inches
4.01 × 10^(-12) m × 39.37 in/1 m = 1.58 × 10^(-10) in
That’s the SI unit of energy or work
