What would you use to measure an amount of solid chloride (naci) crystals to add to a 30 ml solution? a. scale that can weight up to 250 lbs. b. spectrophotometer that measures between 100 and 900 nanometers. c. 10 ml graduated cylinder. d. triple beam balance that measures to the nearest 0.1 grams

I'm pretty sure its B.) Spectrometer that measures between 100 and 900 nano meter. Because the other answer i was looking at that i thought that could be right would be C.) 10 ml graduated cylinder. But you would need to add 30ml a liquid so the only answer i thought was correct would be (B.)

Option D, Triple Beam Balance that measures to the nearest 0.1 grams

Explanation:

A Triple Beam Balance can measure  mass of substances very accurately with a reading error of either + 0.05 or - 0.05.

For this case,  a measurement device is required which can measure the mass of small quantity of salt for dissolving in 30 ml of solution.

A graduated cylinder measure volume, thus it is not useful in this case. A Spectrophotometer measures the intensity of light, thus it is also not useful. A Scale that can weight up to 250 lbs is not suitable for this case as small weight is to be measured.

Hence, option D is correct.

because of

idk and i also need to know where are those bio brainy acts lol
