What is the distance of the earth from the sun? options are:
15×10⁷
5.8×10⁷
9.8×10⁷
22.6×10⁷

please help me as quick as possible​

15 × 10⁷ is the correct answer.

92,955,887.6 miles

150,000,000 kilometers.

i believe the answer is 15*10^7

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"
