Answer:

The correct answer is A)

Explanation:

An NMR or Nuclear Magnetic Resonance Spectrometer is an equipment that can be used to study the nature of molecules after their nuclei have been excited with the use of radio waves. Radio waves generated is converted into nuclear magnetic resonance.

The resonance produced can be recognized or decoded by special radio receivers.  

Besides recognizing the molecular structure of a chemical compound, it's purity and its content can also be analyzed.

Cheers!

A slice of Swiss cheese contains 48 mg of sodium
Nookie1986 [14]

Answer: grams=0.048g, ounces=0.0017oz, 0.00011lb

Explanation:

Stoichiometry

48 mg x  1 g

          ÷  1000 mg  = 0.048 g

48 mg x  1 g            x 16 oz        

          ÷ 1000 mg  ÷ 453.6 g     = 0.0017 oz

48 mg x  1 g            x 1 lb        

          ÷ 1000 mg  ÷ 453.6 g     = 0.00011 lb

A small hole in the wing of a space shuttle requires a 15.9 cm2 patch.
Rzqust [24]

The patch area in square kilometers is 1.59*10⁻⁹ km₂

Why?

This is an unit conversion problem. We have to convert from cm² to km². We can do that by knowing that there are 100 cm in 1 m, and 1000 m in 1 km, so 100000 cm=1km. Knowing that we can apply the following conversion factor:

15.9 cm^{2} * (\frac{1 km}{100000 cm} )^{2}=0.00000000159 km^{2}

Now to convert this value to scientific notation, we have to move the decimal point to the right until we get a whole number, and the exponent of the number 10 is going to be the number of spaces we moved to the right (negative), so the final answer is:

0.00000000159 km^{2}=1.59*10^{-9} km^{2}

Have a nice day!
