The mass of an object is 100 mg. What is the object's mass in kg?

0.0001 is the objects mass because you go from mili, to centi, deci, gram, deca, hecta, Kila. that's 6 decimal points which is what times you 3 zeroes before the 1. The decimal point started out at the end of 100 and moved 6 places to be 0.0001

Answer:

100 mg is equal to 0.0001 kg

Explanation:

When doing conversions, you always need to remember the units you are working with. So when going from mg to kg, there are a lot of zeros to take into consideration.

1. mg to g:

When converting from milligrams to grams, you divide by 1000, because there are 1000 milligrams in 1 gram.

100 milligrams is equal to (100 ÷ 1000) grams

= 0.1 grams

2. Then converting g to kg:

When converting grams to kilograms, you once again divide by 1000, because there are 1000 grams in 1 kilogram.

0.1 grams is equal to (0.1 ÷ 1000) kilograms

= 0.0001 kilograms

One way to determine the pH of a solution is to measure the concentration of the acid and base forms of the indicator colorimetr

ki77a [65]

Answer:

pH = 4.26

Explanation:

Bromocresol green is a commonly used pH indicator. The concentration ratio of the acid form to base form explains its color, which reflects the pH of the medium.

C₂₁H₁₄Br₄O₅S + H₂O ⇄ C₂₁H₁₃Br₄O₅S⁻ + H₃O⁺

acid conjugate base

We can calculate the pH through Henderson-Hasselbalch's equation:

$pH=pKa+log(\frac{[base]}{[acid]} )=4.66+log(\frac{1}{2.49} )=4.26$
