Answer 1

Answer:

heyya bts army here is the answer:

Explanation:

Molar mass of MnOx = 55 + 16(x)

Now you can see that Molar Mass of Mn(manganese) becomes= 55

manganese Percentage = molar mass of manganese/molar mass of compound  x(multiplied by) 100 = 55 X  100/ 55 + 16 x

64 =  55 X  100/ 55 + 16 x

64(55+16x) = 5500

3520 + 1024x = 5500

1024x = 5500-3520

1024x = 1980

x= 1.9335 = 1.93

hence your answer is option D).
