Title: Urgent conversion *delete me*!
Post by: alyssanda.vo on March 15, 2021, 08:47:16 AM

Given a mass of 2.785 g of water, at 22°C, calculate the volume of water in μL.

I calculated it to be 2785μL. Am I correct or not?

If the specific gravity of water at 22 ° C is still 1 g/cm^3 then it is correct.

Thankyou, I also have another question

Does using lambda max during analysis of a solution, does the use of the labda max:
1. minimises the impact of background and instrumental interference
2. the response of the instrument will be most sensitive at lambda max

Thankyou!

I would say no. 2
