Answer:
The options are not really clear, however, the answer is 3.2 × 10^3ug
Explanation:
Milligram (mg) and microgram (ug) are interconvertible measurements of mass or weight. One microgram (ug) is a millionth gram while one milligram (mg) is a thousandth gram.
Hence, one milligram is a thousandth microgram i.e. 1 mg = 1000 ug
Therefore, a measurement of 3.2mg in ug will be; 3.2 × 1000
= 3200
= 3.2 × 10^3 ug
Hence, an equivalent measurement of 3.2mg is 3.2 × 10^3ug.
The equivalent of 3.2 mg is 3.2 x 10^-3 ug. Therefore, the correct answer is option c.
3.2 mg stands for 3.2 milligrams.
The prefix "milli-" means one-thousandth (1/1000), so 1 milligram (mg) is equal to 0.001 grams (g).
To convert milligrams (mg) to micrograms (ug), we use the following conversion factor:
1 mg = 1000 ug
So, for 3.2 mg:
3.2 mg * 1000 ug/mg = 3200 ug
Now, to express this in scientific notation, we can write it as:
3200 ug = 3.2 x 10^3 ug
So, the correct equivalent of 3.2 mg is indeed:
c) 3.2 x 10^-3 ug
therefore, The correct answer is option c.

Answer:
116
Explanation:
neutrons = mass number - proton number
66 = mass number - 50
add 50 on both sides
66 + 50 = 116
so the mass number is 116
Answer:
2×10^-5L
Explanation:
Since there are
1000mL in 1L
0.0200mL will give us
0.0200/1000
= 2×10^-5L
To convert 0.0200mL to liters, we use the conversion factor 1L = 1000mL. The calculation becomes 0.0200mL divided by 1000, which equals to 0.00002L.
The given question asks, how many liters are there in 0.0200mL given the conversion factor that there are 1000mL in 1L. To calculate this, we will use the known conversion factor and divide 0.0200mL by 1000. Here are the steps:
So there are 0.00002 liters in 0.0200mL.

The Answer Is True :) Took The Test:)
The answer is electrolyte.
That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.
Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .
The best name for the compound is DINITROGEN TRIOXIDE.
Each chemical compound is always represented by a chemical symbol, which shows the ratio at which each atom of the elements of the compound are combine together and this is often used in naming the compound. Looking at the compound given in the question, the compound is made up of two atoms of nitrogen and three atoms of oxygen and this fact was used in naming the compound. In naming chemical compounds, 'Di' stands for 2 while 'Tri' stands for 3. Since there are two nitrogen and three oxygen atoms in the compound, that was why it was named dinitrogen trioxide.
