Ответ:
157.8g/mol
Explanation:
Mn2O3
Molar mass = (54.9*2) Mn + (16*3)O
= 109.8 + 48
= 157.8g/mol
Ответ:
100x
Explanation:
The actual power or magnification of a compound optical microscope is the product of the powers of the ocular (eyepiece) and the objective lens. The maximum normal magnifications of the ocular and objective are 10× and 100× respectively, giving a final magnification of 1,000×.
