gregori [183]3 years ago
6 0

Answer:

0.188mol

Explanation:

Using the formula;

mole = mass/molar mass

Molar mass of hypomanganous acid. (H3MnO4) = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

According to this question, there are 22.912g of H3MnO4

mole = 22.912g ÷ 122g/mol

mole = 0.188mol

Imagine there is less gravity on Earth for
Bond [772]

Answer:

Three ways that I would make most of this situation are going near an area to avoid the things drifting into space. I would seek shelter in a basement. I would also stay indoors.

Earth's atmosphere and its oceans, rivers, and lakes would be one of the first things to drift away into space, we would need to avoid those obstacles by seeking shelter. The first problem is that Earth is rotating at high speed, rather like the way a weight on a string rotates if you spin it around your head. Anyone unfortunate enough to be outside at the time would quickly be lost. People inside buildings would be safer because most buildings are so firmly rooted to the ground that they would stay put even without gravity – at least for a while.
