Answer:

2.0202 grams

Explanation:

1.4% (m/v) glucose solution means: 1.4g glucose/100mL solution.

so ?g glucose = 144.3 mL soln

Now apply the conversion factor, and you have:

?g glucose = 144.3mL soln x (1.4g glucose/100mL soln).

so you have (144.3x1.4/100) g glucose= 2.0202 grams

Which of the following electromagnetic waves are listed in the correct order from longest wavelength to shortest wavelength
Ghella [55]
Good afternoon,

Infrared light wavelengths = 1,000 nm - 750 nm

Visible light wavelengths = 750 nm - 400 nm

UV (Ultraviolet) light wavelengths = 400 nm - 10nm

So, the correct order is Infrared - Visible - Ultraviolet

I hope this has satisfied you, and if you need anymore help, feel free to ask.

Have a good afternoon!
