Astudent analyzed a viral genome and found that the genome had the following nucleotide composition.
• 28% adenine
• 20% thymine
• 35% cytosine
• 17% guanine which of the following best describes the structure of the viral genome?

c. the scientist provides unbiased information to the government.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

m=9

step-by-step explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
