To determine the cost of consuming 10 mL of a sodium hydroxide (NaOH) solution at a concentration of N/10, we need to break down the components involved in calculating the price. Let's go through this step by step.

Understanding N/10 NaOH Solution

An N/10 solution of sodium hydroxide means that there is 1/10th of a normal concentration of NaOH. In practical terms, this means that for every liter of solution, there is 0.1 moles of NaOH. Since the molar mass of NaOH is approximately 40 g/mol, an N/10 solution contains about 4 g of NaOH per liter.

Calculating the Amount in 10 mL

To find out how much NaOH is in 10 mL of this solution, we can use the following calculation:

  • 1 liter = 1000 mL
  • Concentration of N/10 NaOH = 4 g/L
  • Amount in 10 mL = (4 g/L) × (10 mL / 1000 mL) = 0.04 g

Cost Calculation

Next, we need to know the price of the N/10 NaOH solution. Prices can vary based on the supplier and location, but let’s assume a hypothetical cost of $10 for 1 liter of N/10 NaOH solution. To find the cost for 10 mL, we can use the following formula:

  • Cost per mL = Total cost / Total volume
  • Cost per mL = $10 / 1000 mL = $0.01 per mL
  • Cost for 10 mL = Cost per mL × 10 mL = $0.01 × 10 = $0.10

Final Cost Summary

Therefore, the cost of consuming 10 mL of an N/10 NaOH solution, based on our assumptions, would be approximately $0.10. Keep in mind that actual prices may vary, so it's always a good idea to check with your supplier for the most accurate pricing.

Practical Implications

Understanding the cost of reagents like NaOH is crucial in laboratory settings, especially when budgeting for experiments or projects. This calculation not only helps in financial planning but also in understanding the scale of chemical usage in various applications.
